Philco 41-280
#13

So it's working properly? Leave the 20mf in replace the 8mf with 10 or 20mf. You'll find when you get the caps fixed up and now that you have the grid bias on the 41 tubes the HV will be more in line with what the manual sez. Without bias on the 41's the plate circuit will draw excessive current thus dragging down the HV line.

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!
