Baldwin Output Transformers FS

Postby Blair » Sun Oct 28, 2012 9:09 pm

I have a pair of these transformers I'm looking to sell due to a rebuild using the rest of these parts. They are in excellent condition with no dents and great original paint. If I recall, they are 3.8K with an 8 ohm speaker tap. Rated at 40W. I have used these for both EL34 and 6550 in triode. The pair in the images are the ones for sale. I will pull them to ship.

Asking $75 shipped for the pair.

Open to reasonable offers as well.

Thanks!

Curious as to the mounting hole dimensions, alleged freq response for hifi and confirmation of whether UL taps or not (I assume not), thanks.

8 ohm secondary ONLY, correct?

Hi Tom,

2.25" X 2.25"

On a calibrated HP339A, I got roughly 30hz-17K +/- 1db.

Correct. No UL taps. That's why I have used them for triode strapped output stages.

Thanks!

3.8K primary would be a good match for PPP EL84s / 6GK6s, too [:)

Do those have identifying numbers on them? I've heard there are (at least) two different versions of these.

Hi,

The numbers are:

F-c512-23668
512-23668A

They both had 7027s driving them, identical laminate stacks and measured the same.

I can pull the primaries and measure the turns ratio again if you want to be certain of the primary impedance.

Thanks!
