Power amp tubes
« Thread started on: May 4th, 2009, 01:36am »
I am just after information if anyone has it. I am presently using a soldano SP 77 into the power amp section of a marshalll mk 2 super lead. The power amp valves have not been changed for 10 years. What sort of differences and were likely to hear if I go to the trouble of changing them and biasing the amp?
