Squeezebox Touch Powersupply

[Darren]

It was my birthday on Monday.... I dont want to talk about how old I am:(:cocktail::acid:

The only upside is that I've bought myself a Squeezebox touch and Im kind of excited about getting some good sounds from a few FLAC files. Im also planning some value for money upgrades just for fun:)

I have a couple of DACs a can use so no problem there. But Im also wondering about a low cost upgrade to the basic power supply. I aint springing for £200 of Teddy Touch supply so I had a google and found this from Russ Andrews:
[URL="http://www.russandrews.com/product-TouchPak-for-the-Logitech-Touch-1834.htm"]
But for what you get it too seems a bit steep. Has anyone any experience with alternatives?
Any suggestions valued and explored!
Thanks.
Darren

Have a look at the Squeezebox Touch forum Darren:

I have a home made supply based on the John Swenson design that does improve the performance of the Touch.

[Butuz]

£93 for a bog standard switch mode PSU with one cap changed and some fancy cable?

Oh dear.

Make/buy a non rip off linear PSU.

Happy (belated) Birthday, Darren!

:birthday:

[Darren]

Ha, ha!! Many thanks Alex thats very nice of you. :cheers:

Butuz - that was my own thought. its hard to see the value in that.

Hey Cov - thanks for the link....mmm: they dont seem to think that a new power supply will make any difference. Interesting.

[Ali Tait]

Oh, but it does!

[Darren]

Hi Ali,
Even when I'm using an outboard DAC?

[jbloggs]

Oh, but it does!

Which PSU are you using with the Touch?

[Gazjam]

Oh, but it does!


Absolutely does.
I've heard the linear PSU Ali uses in my own system.
I was sceptical too...but it was an obvious improvement from the stock supply.

Honest. :)

I always trust my ears rather than what I read, and in this case the Touch can be made to sound better with a linear supply.
Theres more to it than just switching vs linear of course..but
it DOES respond well to a good PSU.

Honest :)

[Ali Tait]

Well it's actually a switching supply, but a good one. I managed to liberate a few from my last place of work. They are nemic lambdas, and I got about half a dozen at various voltages, luckily two are what I need, one being 5v which runs the Touch, and another at 15v which runs my two Bantam Golds, which again was obviously better than the stock wallwart.

[Darren]

Ok! I'm convinced. Could anyone suggest an off the shelf item I could buy as construction is beyond my ability?

[Ali Tait]

Keep checking ebay, various ones come up now and again. There are also bench supplies, but they can be a bit pricey.

To answer your earlier question, yes, even with an outboard dac it's an improvement. I use an Audionote dac.

[Darren]

I had an Audionote DAC 1.1 a few years ago. It was as sweet as a nut. Loved it.
I'll keep my eye out for a supply but if anyone knowsof anything do please give me a shout.

[WAD62]

I've been using these with my SB receivers with great success...

http://www.maplin.co.uk/ac-dc-multi-voltage-20w-power-supply-32754

...it's a variable voltage linear PSU, with settings of 1.5,3,4.5,6,7.5,9 & 12 Vdc, the SB receiver is 9V so it's fine for them (N.B. the web site states 5V as an option, I believe this is in error).

I also have an SB3, which like the Touch requires 5V, so as an electronics numpty I'm wondering if I could use one of these with it, with a little alterartion :eyebrows:

The voltage selector is just a dial on the top, set with a screwdriver, could this be used to select any voltage in its capable range, or will it have specific spots associated with specified voltages? :scratch:

Time to call Maplins I think...

[wee tee cee]

I followed wills advice and noticed an improvement over the origional.I paid about £18 at maplins.
TC.

[Ali Tait]

I'd guess the Touch should work ok with 4.5v.

[WAD62]

I've just been on the blower to maplins HQ;

There would appear to be some confusion at maplins about the VN10L...

They have 3 different suppliers and three different product codes (none of which are on the box), the ones I bought for my SB receivers (9V) about a month ago were discounted to £12.99, have a red maplins label on the device, and cover 1.5,3,4.5,6,7.5,9 & 12 v range.

The ones in the Coventry store are as above, but now at £18.99

The current one advertised on the web page has a blue maplins label and cover 5,6,7.5,9,12,13.2 v range. Perfect for my SB3 and for the touch too!

So the question is how can one acquire the updated one?

Maplins are apparently going to get in touch with me, I'll post their response if I get one :eyebrows:

Tony what does your recently bought VN10L look like, what voltage options does it offer, and is the maplins logo red?

[WAD62]

I'd guess the Touch should work ok with 4.5v.

Wouldn't that cause some problems Ali? remember my numpty knowledge...

Also couldn't it be tweaked to give 5v as it's variable voltage anyway :scratch:

And even more hopefully, if the new one goes up to 13.2v could it be beefed up to 15v for a beresford DAC perhaps

[Darren]

Oh ho! Now we are talking. :)

[clive7164]

I imported one of these and could hear an improvement

http://www.welbornelabs.com/squeeze.htm

they had 20% off when I bought mine and the pound was at over $2 to the pound so it was a good price then
may be a little much now

This was the (Touch) PSU that I mentioned and linked to in This (http://theartofsound.net/forum/showthread.php?t=9135&highlight=touch&page=4) thread, however, the one comment made about it was rather terse...

[Darren]

Just as a wee aside boys....
Which file format do you prefer: WAV or FLAC?
Space isnt really an issue so it's down to sound quality. Have you heard any difference?
Thanks in advance.

You shouldn't be able to hear a difference between FLAC & WAV and of all the testing I have done between the two I cannot tell the difference, so I only have FLAC for the reduced library size. There are members here who keep both, but play FLAC, with the WAV file is a backup. I guess at the end of the day, try them both and see, but I doubt you would be able to tell the difference in a blind test?

And I can't tell the difference between WAV and FLAC either ;)

I'm sure it sounds good, but a power supply that's more expensive than the device it powers, is a little excessive IMHO...;)

Oh and whilst I'm here FLAC, FLAC, FLAC, FLAC, etc...:)

Whereas if you order from the web site you will receive the new version which is the 5,6,7.5,9,12,13.2 v range version.

I've just ordered one for my SB3, 5V, it also may be OK for a Beresford as it now goes up to 13.2V :):):)

Happy days! :cool:

[jbloggs]

I'm sure it sounds good, but a power supply that's more expensive than the device it powers, is a little excessive IMHO...;)


I don't look at it that way...

My system cost me >£2000, so I look at what upgrades will improve the sound quality and at what cost, in the case of the Touch PSU it would appear that replacing the stock one yields a decent improvement, in my system I don't see how I would effect a better improvement for spending this money on the Touch PSU elsewhere.

I also note that spending £60 on a Mark Grant power cable (http://markgrantcables.co.uk/shop/index.php?main_page=product_info&cPath=45_18&products_id=69) is not frowned upon but looked upon as a sound investment here on AoS (which I agree with), however, persons could point out that spending £60 on a simple bit of cable is wildly excess and pointless!


I've just ordered one for my SB3, 5V,

I will be interested to see what results this gives.

[WAD62]

I will be interested to see what results this gives.

I already have two of the original model for each of my SB receivers (@ 9V), and they give tremendous improvements for both the digital and analogue outputs.

As I mentioned in my original post :)

FYI Check out posts 14 & 15 & this thread http://theartofsound.net/forum/showthread.php?t=10134

We'll see what happens with the SB3, fingers crossed :eyebrows:

I like the 'economy of scale' that maplins gives :cool:

P.S. We've all spent a lot of money on our systems here, it's just a question of what that money gets you, and for the £200 you've spent on a linear PSU for your touch, I've got 3 for my SB players, 2 more for my T-Amps, and have change left over for a Beresford DAC...Oh and a trip round t' world on't QE2 ;)

The TTouch is based on the same TeddyCap power supplies for Naim equipment utilising the SuperTeddyReg.

[Reid Malenfant]

The TTouch is based on the same TeddyCap power supplies for Naim equipment utilising the SuperTeddyReg.
So if it's the same as the SuperTeddy regulators i have seen it's a cascaded (2 section) series regulator. Shunt regulators are incredibly inefficient unless you are nearly drawing the full design current, requiring huge heatsinks ;)

No but I started a thread a while ago on the subject, and after some good input from more electronically minded people on AOS I moved towards the cheaper maplins offering...what is that filter thingy? Probably a ferric ring in a posh box...

Perhaps I'm just too cynical ;)

It is indeed Jon...one small downside, the one I ordered arrived very promptly, unfortunately it's the original spec not the web site one...i.e. it doesn't do 5v only 4.5v etc.

So 'buyer beware', fortunately I've blundered into success again, the beresford DAC I'd recently bought needs 12v (I thought it needed 15v), and the old one does that too, so I'll be keeping mine.:)

[Jonboy]

Ah good if i get 5 mins this week i will pop into my local Maplins and grap one to try out

[captain]

Here you go the teddy PS is the one on the right the other transformer on the left is for another power supply that I got built by some else to power the upgraded clock in my SB3. Some of the caps on the TPS have been upgraded to better ones which includes the bigger cap.

[Gazjam]

Reviving this thread to ask about another Maplins PSU as a potential replacement for the 5V 3amp one supplied with the Touch.
http://www.maplin.co.uk/ac-dc-multi-voltage-4a-switched-mode-power-supply-48517

Can set it to run 5V DC at 5 amps and its a regulated supply, so should mean voltage pretty stable and is as stated?
Just curious to try it, as its sitting in a box doing nothing. It will also let me use my foo mains lead with my Touch, which may or may not make a difference :)
(Actually, the mains lead made an good improvement with my old amp, so suspect it wouldn't do any harm)

The Touch runs 5V and the supplied PSU is rated at 3 amps I think.
I'm assuming the Touch would only draw what it needs amp wise...no problem with the Maplins supply being 5amps?

Just curious if it will physically work and not blow up my Touch!
The numbers seem ok?

Just curious to try it, not expecting much.

Hi Gaz I'm using one of those on an SB3 quite successfully, at 5V, and no smoke has eminated from it yet;)

However this linear one is even better IMHO, if it ever filters through to the shops...

http://www.maplin.co.uk/ac-dc-multi-voltage-20w-power-supply-32754

...I've got 3 of it's predecessor, which didn't do 5V (the closest was 4.5), but does the 9V requires for my SB receivers, and 12V for my TC-7510.

Check with the shop first as there seem to be a lot of the older spec out there in the stores, with the same model number :steam:

[Canetoad]

I'm running my Touch on this and it works fine. I haven't done any direct comparisions with the original though. I had it spare so used it on the Touch set to 5 Volts. Try it and see what you think. :)

Make sure you get the polarity right though. The arrow on the connector should point to the + on the plug.

[Gazjam]

Cheers for that Will.

I read about the schenanigans with different versions of that supply..whats that all about?
Good to know I can try my Maplins supply with the Touch.

I've read elsewhere that the SB3 and Touch aftermarket supplies are pretty much interchangable, and (more importantly) that any device will only draw whatever current it needs, and as long as its fed the right voltage things should be ok.

Also, this Mplains supply is regualted and voltage should be stable.

*EDIT*
Hope I can find a tip to fit the Touch power input!

Give it a whirl anyways.. :)

Works fine, sounding good. (great actually)
Radio Paradise at 192k tinkling away in background, will plug standard Touch PSU in tonight for a quick compare.

Not going back to the original Touch PSU.
Cleaner more dynamic and solid sound with the Maplin/foo cable in place, even better when plugged into a Tacima mains block.

That'll work :)

Ok Maplins have just got back to me about the VN10L.

As suspected they're changing their supplier the...

1.5,3,4.5,6,7.5,9 & 12 v range version is old stock and still in the stores.

Whereas if you order from the web site you will receive the new version which is the 5,6,7.5,9,12,13.2 v range version.

I've just ordered one for my SB3, 5V, it also may be OK for a Beresford as it now goes up to 13.2V :):):)

Happy days! :cool:

I checked in with my local Maplin store yesterday, they still had 7 of the old/ red model in stock (they said they usually only carry a couple), so it may be a while yet before new / blue reaches the stores.

They do have this one on offer until 8.00pm tonight, it does 5v but seems a lightweight affair compered to the VN10L, which is a much more solid, confidence inspiring job.

http://www.maplin.co.uk/worldwide-ac-dc-multi-voltage-3600ma-power-supply-48908

[degsy]

I also tried my local Maplins for the VN10L model as a replacement for my 7510 Mk IV power supply - thinking of utilising the 13.2 v output option. Was on the point of parting with cash when I noticed that the top voltage option quoted on the box was only 12v, so old stock.....and there were a few similar boxes on the shelf!

Then considered ordering the website model, but given the previous comments I am not convinced that I will receive the newer version.:(

Perhaps I should plump for the more expensive model :scratch:

Only if you want to gain nothing or make it worse!!!

The point of replacing the psu is to get from a noisy SMPS to and much quieter linear supply. The maplin linear supplies should be better than the std smps but you can do much better. You dont need to spend a fortune on a commercial PSU if you can do some basic diy electronics. Even using a fixed 5v maplin supply as a base and adding a commercial decent low noise reg will be an enormous upgrade.

If it were me I build from scratch. :rolleyes:

50va 2x9v toroid transformer, Schottky Diodes for bridge rec, Audio upgrades (F&T) 22,000uF extremely low esr Cap, SPower 5v reg and a case. All for under £100.

This is my own SB3 PSU. Its a 50va 9v tx capable of delivering 5.5A, hexfred diodes and then 2 x 22,000uF panasonic TSUP. It then runs 1 SPower 5v low noise reg for the main feed to the SB3 (minus the display), 1 std 7805 reg for the display, and an unregulated supply for the internal clocks.

One of the beauty's of the SB touch is that you dont need to separate the display as its not the HV fluorescent type. Therefore there will be no requirement for the additional display supply. A single low noise regulator is all that will be required.

Make no bones about it, any of the commercial PSU's will be no more than a large transformer, recs, cap, low noise reg of choice and a pretty case!!!

Hey Ian that looks sweet!!!!

I fancy a bit of a DIY project myself. Where did you get the PCB from for yours??

[UV101]

This is the pcb. It's sold as a dual (+/-) board but it can be modded with a wired link to run a single supply full wave.

what you end up with is comparable to a commercial psu, without the development costs, labour and marketing! ;)

Then considered ordering the website model, but given the previous comments I am not convinced that I will receive the newer version.:(

Perhaps I should plump for the more expensive model :scratch:

Any experiences/views?

I have that one of these too, I bought it for a T-Class amp, it's still a switched mode one however @ 60W, more than necessary for the SBs and Beresford. Currently I'm using it on my SB3 which requires the same as the touch, I'm waiting for the new 5v capable VN10L to filter it's way into the shops too.

I prefer the VN10L on my Squeezebox receivers (9V), and Beresford (12V), @ 20W linear, which is more than enough for them.

Either would be an improvement IMHO, but the VN10L ticks more boxes for me, and it's cheaper ;)

Not sure how that Maplins PSU will be with the Dac, but I swapped it over for the stock SB Touch supply and found it better.
Its what I use now on my Touch.

Are you using the SMPS version? I thought the point was to move away from a noisy SMPS and get linear?

No doubt, but I happened to have the supply around the house unused, thought I'd just try it anyway to see if it made any difference.
Its better than the stock PSU.

It lets me use a "foo" mains lead (Krystal Kables Titan:v.good) with my squeezebox...but thats a different story :)

A linear supply is still on the cards for my Touch, but not in any rush to replace what I have already.

On my SB3 yes, because the new 5v capable linear VN10L is not in the shops yet...when it is available I will use it on my SB3!

Please refer to my earlier posts for details

This is the pcb. It's sold as a dual (+/-) board but it can be modded with a wired link to run a single supply full wave.

what you end up with is comparable to a commercial psu, without the development costs, labour and marketing! ;)

Where would the wire link go on the PCB Ian? :scratch:

The AC will go into AC1 and AC2 (no transformer connection to the 0v in the pic). Connect the GND to the DC negative rail together and only use the space for 2 caps in the positive rail. Take you DC output from + and gnd.

Thanks Ian, that's great! :)

No Problemo ;)

Can anyone confirm what the standard DC voltage is for the Touch please? Poss even a photo of the PSU label?

Thanks :)

It is 5 volts. Positive to the centre pin of the plug.:)
