I find it wise to check every few weeks.
Follow Ups:
I would be afraid of such a conclusion that I have to check the tubes with any frequency greater than 120 days or at all.Damn minimalist amps -- well, my next one should have a nice front-panel mounted bias meter and controls!
That when I check it usually has drifted from 1.4 to 1.2 or so. I think it is the vibration from the power tranny!
and switches to check the four tubes' plate current.
I'm constantly flipping those switches and checking the readings.
It's a sickness I Tell YOU! A SICKNESS!
