I'd like to compile a list to get an average plate voltage for each model.
This can help you spot if there is a problem with your amp (i.e. WAY outside the average range), problem with your measurements (equipment or technique), and give us lazy people an idea of where to set bias (using a probe of course) without poking around stuff running at over 400v LOL!

Post your amp model, plate voltage, and your bias (i.e. 40mA)
