Mystery Cap in an early (two 45s) Model 90
#4

Thank you for the schematic. I guess I will just power up the set and see how it goes. May play around with a few different values for the mystery cap and see how it sounds. 

By the way if there is a high Res photo of the underside of an early 90 chassis out there that would be helpful too.
