I need to know asap.... what is the C between the anode and grid of a GS35B....when plugged into a socket. Typ, when they spec tubes like triodes in GG, they spec anode to grid C..... BUT that always rise a bit, when plugged into the grid ring...due to the proximity of the lower anode fins...to the chassis below the lower fins. I'm designing a PI network for a fellow....and don't have a GS35B in my shop. Does anybody know, or can measure the anode to chassis C on their GS35B tube amp for me ? In the case of an existing amplifier, the anode lead to the plate choke needs to be temp disconnected....and ditto with the RF connection, from anode to plate block cap assy. It would be much appreciated.
