I am currently repairing a Univox 1221 tube guitar amp head. The amp "claims" to put out 100 watts with a pair of 6L6GC tubes, (Yeah right.) The schematic shows the plates at 660 volts yet the tube data states 500 volts max for 6L6GC tubes. I always thought that a pair of 6L6GC tubes could put out about 50 watts on a good day if you round up....and could put out about 75 watts with an ultra-linear transformer again on a good day and rounding up.
Is it even possible to get close to 100 watts with two 6L6GC tubes?
I have yet to measure the voltage but if the amp indeed puts 660 volts on the plates (and 320 volts on the screen) but I would assume that high a voltage would eat up the output tubes in a short while.
