Just for grins if you like to experiment a little w/the new transformer installed and the set working connect a small cap from the plate lead to one of the grid leads. I've done this to improve the frequency response on se amps in battery sets. In terms of values something like .005 to .01mfd voltage wise 100v is plenty. This may improve the hi and low frequency response. If it does make an improvement try adding another cap from the plate lead to the other grid lead. This may cause the amplifier to oscillate if so remove the 2nd cap.There are a lot of other factors in the equation so it may not make much of a difference.

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!
