X10-d (modded) psu question (maplin psu in sale)

[The Vinyl Adventure]

Went up to maplin for some bits of modding my dyns - needed 16 banana plug sockets ... They had 3 ... Useless!
Anyway whilst there I noticed they had 15v 4amp smps in the Christmas sale - little sign saying "ideal Xmas gift - was £34.99 now £19.99. I'm not sure in who's world a smps is a "ideal Xmas present" ... Still I was happy to find it as it will provide my x10-d 12v and 5amps if it need it.

My queery is - I'm sure I read somewhere 13.5v would be better for the x10-d - what is likely to give me more benefit 12v and 5amps or 13.5v and 4amps ... Is it safe to just suck it and see, I don't want to break anything!

[Stratmangler]

The answer to your query is...............

























...........the X10-d will not be drawing anything like 4amps, so either voltage should suffice.
If it goes pop on 13.5vdc don't blame me - you suggested it first.

[Reid Malenfant]

Can i ask what an X10-D is? I might be able to give you a better answer ;)

[Clive]

The X10-D expects AC. A simple but hefty transformer is all that's needed.

Clive, could you be decent enough to fill me in on what an X10-D is?

I have heard of an X1, X2 & X15, but obviously they are nothing like an X10-D unless Hamish has a secret rocket plane building program going on we know nothing about :eyebrows:

Thanks for the possible reply :)

[Clive]

Sure Mark,

It s valve buffer, high impedance input, gain 0.9.

One of those impedance matching thingys we're told we can't do without! :)

Thanks for the tip Hamish, I'm sure the wife will love it instead of all that tacky gold and diamonds she usually wants - I can't wait to see her face! I owe you one!

[Reid Malenfant]

Thank you Clive :)

Valves on 12V??? WTF :scratch:

From now on i'll keep my nose out but frankly i'm surprised, as they need an AC input is there some kind of step up transformer or voltage doubling/tripling going on?

I fully agree that if this is the case then only feed it AC or it won't work :eyebrows:

[Clive]

Yes, there's a voltage doubler, it ends up with 30-odd volts on ECC88s, IIRC.

Clive (who once owned my X10-D) is quite correct about 12V-AC.. I used a Christmas tree 4A supply for a while until my home made one was done. That wall-wart is a bit naff tbh...

I had a thread here regarding my X10-D conversion, but here's a pic or two...

and the temporary transformer I found.

Dave,
It's either nicely re-sprayed or you've hidden the part that suffered the accident with the logging saw.:)

[DSJR]

I turned the case round. Hidden in the cabinet, the marks cannot be seen. Love it and the Croft's tape output really appreciates the buffering ;)

[The Vinyl Adventure]

Ah I see ... So it's not suitable anyway ... Fair enough ... I'll try again

My old valve radio worked on a 12V Berec battery. Alrite, so some of you might be too young to remember the Berec brand:lol:.

[RochaCullen]

Is this the smps:

Looks like something that would work well with a gainclone amp. Although not sure the 15v would be enough.

[StanleyB]

It's the power supply that used to be £19.99. But then I recommended it as an upgrade fro the original TC-7510 DAC, and soon after that Maplin increased the price to £34.99.

[DSJR]

I should have tried one with the Lentek, as I spent about the same ampount buying an ABS case, sockets, transformer and ebay regulator, only to find the regulator not quiet enough. I hope it will be ok for two J-FETS on my basic high input impedance line driver..
