WTB - Power Supply transformr
#1 WTB - Power Supply transformr
Anyone sitting on small, decent quality, power supply transformer with a 120VAC secondary they might part with. By small I'm thinking 50VA - 100VA range, Primary for UK mains.
Ta,
Ta,
Sorry, I couldn't resist!

I thought I might have, but I can't find the one I'm thinking of.
I did find one I'd forgotten about but it's only 115v output @ 80va, and it's a non isolating auto wound transformer of unknown quality. The output is via a socket which looks like a USA 2 pin with an extra hole.
I can take a picture if it helps, but it won't be till tomorrow afternoon.
Yours for nowt if it suits your purpose.
I'll have a search for the missing one when I get back from my walk early afternoon Thursday.

Sitting up in bed I remembered where the "other" transformer was stashed.
It's an auto transformer (non isolating) from Walsall Tx, model ATX2250A, 250va 50/60Hz.
The input has 4 terminals,E, 0, 220v, 230v, 240v
The output is 0 and 115v, but using the 220v or 230v input will raise that a bit. I've had it for years but never found a use for it.
Again, it's yours for nowt if it will do what you want.
PS It's not small, or light. I can measure and weigh it if necessary.

Cheers Phil, I think the small one will do the trick - I need to build a power supply to test a preamp circuit build.

Say no more Ray, I'll get it packed up and posted, probably on Monday.
I take it you haven't moved recently ?

Still in the same hovel Phil! Thanks.

#7 Re: WTB - Power Supply transformr
Unless I have misread, the fact they are autoformers and so not isolating would make me not use them. Consider someone wiring a mains plug incorrectly...

Ray, I won't be offended if you want to change your mind.

I just want to test the preamp for now so not the endgame.
