Thank you for reply -- but I am now beginning to doubt if there is not another underneath problem or 'collaterial damage' involved. Last night, I played the amp for about 5-7 minutes. Bias light is on and fine -- but the bass-like, 'thump'/two came back/re-occurred and with a very slight acrid smell. This tells me that perhaps there were either two separate occurances/problems or collaterial damage when the 6C33B-C failed. All in all, I believe that it is likely that a resistor was stressed previously, started to fail over time and with the tube failure?, the outside covering of the resistor started to wear/burn, causing the smell. So, I think that I may have a bad/worn resistor problem also -- which should be localized on the board in the area of the bad tube/bias light etc. What are your thoughts? I turned the unit off immediately -- I did not want to risk further problems if indeed I had a bad resistor.
