Definitely helping and thank you for that, and if I may throw in a few other questions:

It looks like the output transformer primary is also connected to the cutter head. Is this because of the crystal cutting head needs more power than a magnetic head?

And the cathode bypass capacitor.. can that capacitor be a non polarized electrolytics? I see that on this schematic is a polarized one but when I check a Fender Champ schema, looks like the bypass cap is a non polarized 25mfd eletrolytic capacitor.?

Thanks !
