I am joining this Forum because I need to set the bias on my vacuum tube amplifier. It appears I need a miliamp meter reading up to 500 mA. I don’t know where to buy one. Amazon does not have any. Can anyone of you guys give me some ideas? Thanks, Richard
Bias adjustment on solid state amplifiers
Why is there no mention of this in manuals, etc, with solid state amps? It seems with tube amps, there's a built in way to do it and/or mention of it in their manuals.
