[QUOTE="ludo, post: 46578, member: 691"] Ampdog, some very noobish questions around the periphery. The approx 58V DC offset on the AC heaters is there to protect the ECC81 from having more than 90V between cathode and heater, yes? Does it have any other benefit? Any particular reason to not make it higher/lower within the limits of the EF86? Do heaters more positive than the cathode rob electrons emitted from the cathode or is that not a concern? Would that for instance change the offset voltage on the heaters then? [/QUOTE]
