Hi
I am fixing up an old Gretsch Electromatic amp and came accross something I have not seen before and can not find on any other amps. On the power amp, PP 6V6, the cathodes are tied together and then have the normal resistor to ground shared between the two of them. The odd thing is tied directly to the cathodes is a lead from the power transformer. It is a green lead which is very often the sheild, but if it is that, or something else, why would it be tied to the cathode?
In general this is a kinda weird amp. When I have some time to scan I will post the schematic and some pictures for those of you who would be interested.
thanks,
adam
