That is a good point. I thought about that too. I am still learning. I have never changed a tube in either that amp or in the Gemini. I just don't use them that heavily. But I am thinking I will go back to a single bias resistor and bypass cap. The power dissipation calculation for the tubes differed by about 15% so I thought I would even that out somewhat. I am not sure it made a difference.....sounded good either way (one vs. two bias resistors values). I will consider going back to one bias resistor and cap. Using a single bias resistor and getting matched tubes would be a good path when new tubes are required. I might leave it as is. I left a note in the amp.
I am just finishing upgrading a SilverTone strat guitar for a friend. The replacement parts came over the past few days, so I can move on to other issues. Also, I found that the treble pot on the Gemini amp is breaking up in the high treble where the pot hits the switch to high treble. Some contact restorer might fix that, but I have to open the thing up to get to it.
Then there is redoing the basement bathroom, but that is another story.
