Tube Amp Archive

Good to know, I had not thought about that and always associated that with no current at all.

I thought the low current could make it susceptible to any vibration of the grid or even Noise emitted from other wires.

Hi, I built some amplifiers using lower than standard voltages with not common tube types and wanted to know if someone knows something about limitations regarding the minimum anode current. For example, I am running a 5678 in triode mode at 65v, biased at -1.5v (fixed bias) and I am using a very la...

I also had problems with my password and created a new account. Creating accounts was not working before too.

@xtian could you also send the reset password e-mail for my previous account (Thomas_H), please?
