[QUOTE="Julia, post: 34758, member: 1784"] I've been thinking about picking up an old oscilloscope to do that with as well. Check his bias when you get the amp home. Write down the numbers. I've found tubes like to drift a bit for a few days. That way you can tweak back to them. My Peavey has a fixed bias. There's an easy bias mod an amp tech may do if the owner wants it biased hotter, otherwise you just pop in a new set of tubes. My tech at Sound West in Tacoma does this "trick" with the 5150s and told me to bring mine in anytime I wanted it done. [/QUOTE]
