Bass circuit problems on model 38-690
#2

Hi Mark
I took a quick look at the diagram and my hair instantaneously burst into flames!!!! A poor of a rendering of the diagram on NA very hard to follow! Generally I would check the pot for shorts to the chassis break out the Signal tracer and start at the pot and nose around a bit to hear if there is any bass boost. Key suspects would an open resistor or cap. I know it's not much to go on.

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!
