PSU Paul Hynes or Timestep

[moodybuilder]

hi all,
at the moment I have removed my power supply and transformer from my 1210 but Im going to get a PSU so what are the pros and cons of either of these or any others. all comments welcome
Cheers

I have a timestep HE power supply that I'm ready to sell if you want it. The HE is the uprated version of the Timestep PSU. As for the pros and cons, you'll need to do a little research around the forum as they have been discussed before.

what are you going to buy and how much you looking for

Hi Phil, I've broached this topic before and read loads here but strangely enough I still wouldn't have a clue which to go for - There are loads out there. Fidelity Audio, Origin Live, Mains R Us did / do one which caught my eye, they now do other options too and then there's more than a few that Paul Hynes does which have always received good feedback. All these are for the beloved Techie - Timestep still do there's (some say the others are better). From between £400 -£500 the list is long but regardless of what I've read I simply still could not determine which one stood out as definate best bang for buck if you know what I mean. Problem is there are so many things to consider with psu's. The spec of many off these off the shelf ones is not always clear or easy to understand. I know that the transformer is a factor also that some have chokes which play a specific part in some too - Maybe now I've said all this a few of my fellow AOS'ers will stick their neck out and recommend one or two for guys like you and I. Incidently from what I've read I do know that I can do better than the base Timestep I have - Lets await responses although the Techie external psu topic certainly isnt a cut and dried one from what I remember :eyebrows:

My recommendation for the Technics is simple - a Paul Hynes SR3 trounces a standard Timestep PSU at (IIRC) very similar price points. I can't comment on the Timestep HE or other PSUs mentioned above, but there's no risk of disappointment with the SR3.

The Paul Hynes SR3 is good, the SR5 even better. In my system the SR3 was marginally better than the Timestep, the SR5 quite considerably better.

Not heard a Paul Hynes PSU but did have a Timestep standard , I now use a Vantage PSU which is quite a lot cheaper but also quite a bit better IMHO .

I happen to have one of Paul Hynes regulators here, it's being used to feed an HDMI matrix switcher & amplifier. While this may seem to have no relation to the Techie, the regulator is of a similar design & is totally discrete components.

In other words it has been designed from the ground up using seperate Mosfets, resistors, capacitors etc to give the best performance possible for the money :)

The regulator in the Timestep HE is an LM317HVT, or to put it bluntly an IC regulator that can be bought for about £1 in a quantity of 100 from places like Farnell or RS components.


And here is the most important, it is all too easily to use a voltage regulator made in China to no particular specification, we use the National Semiconductor LM317HVT low noise regulator

Please feel free to look on ebay where you'll see this regulator mentioned (http://www.ebay.co.uk/itm/Timestep-HE-Technics-SL-1200-SL-1210-Audiophile-PSU-power-supply-BLACK-/250962918521?pt=UK_AudioTVElectronics_HomeAudioHiF i_Turntables&hash=item3a6e8e3c79)

This is a regulator that has been about for probably 20 years & is simply general purpose. The HVT refers to it being slightly higher input voltage capable, T being a TO220 case...

So you pays your money & takes your choice... a £1 regultor in a case for £450+ or a totally discrete regulator designed from the ground up for I know not how much :scratch: Apologies as it's acually £1.09 for 100+ at Farnell (http://uk.farnell.com/national-semiconductor/lm317hvt/v-reg-adj-1-2-57v-to-220-3-317/dp/9485716) :eyebrows:

I know where my money would be going :D

Very good Mark !

Can I add that an LM317 should be used as close as possible to what it's regulating , not in an external case , as I understand it .
