I'm in need of a power transformer with a 120V primary and Secondaries of 230V and 10V, and should handle 10mA or better.

I'm having a hard time googling this, but will continue if I have no alternative.

Thanks for any help.
 
10mA on which winding, 230V or 10V?

It sounds like a custom job for sure. Skipwave was selling some surplus transformers a while back that had similar output voltages (I think the lower-voltage winding was somewhat higher than 10V), but that was a while back and I don't know if he has any more.

What's the application? Is there room for two power transformers?
 
psu for a tube mic.

10mA on the 230V side, sorry!

if I must use 2 trannys, I must, but I'd rather not. could be room, but then I'd probably have to do some Faraday stuff...
Thought I'd try this first.
Thanks for the reply.
 
120:240/12.6 should be all over the place.
Just knock off two volts.
What is the ten volts for?

Post a schemo, whenever you need a part speced.
We might see something that will get you into OEM land.
 
I have got quite a few transformers, but not sure what's all there. two I dug out: a Magnavox television transformer 120v pri, 560v c.t., 5v 3A. you could use one half of the 560 to get 280, and use a voltage doubler on the 5v. The other dated 1964 Fluke a dual 120v pri, 295v, 20v c.t., 134v, and two 6.3v 2.1A, you could connect the two 6.3v for 12.6v c.t. both these transformers measure about 4x5x3.5 inches.
