Output transformer
#8

Hi Rob,
> I know the transformer was out back then already as you could pull one of the output tubes with no effect, but the other would kill the sound. 
The 42 w/the bad winding connected to it is more than likely toasted. With applying screen voltage w/o plate voltage to it make the screen want to act as the plate would BUT it isn't able to handle very much dissipation so it glow red and dies[Image: http://philcoradio.com/phorum/images/smi...wisted.gif].
As one of my friends sez I have short arms and deep pockets I would have given this one a try: https://www.tubesandmore.com/products/tr...output-8-w
I think ratio wise it's pretty close. $50 for a opt ...EECCKKK!

Have a 95 out in the shed myself it needs a tuning cap. Some idiot previous owner took it apart and put it back missing a bunch of hardware. It's near the bottom of the gitterdone list.  Its somewhat unique in that it's the first set to incorporate avc . The 96 is about identical electrically. Technical note when replacing the two 2mf filter cap in the power supply use 630v film caps not electrolytic. They can't take the ripple current for long and will short.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
