I am in the process of completely rebuilding a model 60B radio. My question is about part #8 capacitor, it originally was listed at .18uF but then removed in run number 7 with no replacement but the newer schematic show it was replaced with a .05uF. The model 60B I am using as a reference did not have the .05uF Capacitor. Does any one know if I should add the .05uF capacitor?
Next question is about part #20 capacitor bank, in the radio I am using as reference it appears as if one of capacitors is connected to pin 6 on tube 6A7 which is not what the schematics shows. On the reference radio only one of the .09uF capacitors connects to pin 3 on tube 6A7 and it then daisychains to pin 3 on tube 78, the schematic show each tube gets a .09uF capacitor. Does any one know what is correct? The model 60B I am using as reference is a mid 1936 season radio.
