Thanks, Trev. I changed the question in the post. I found a 6SL7 I did not know I had, but I would need to order a tube socket. I have a good many 12AX7 tubes and sockets which I could also use. Yes, 1/2 of the 12AX7.

I am a little rusty on how to calculate the voltages past the input capacitors. The DC output voltage at the filter input per the datasheet is 360 volts. With modern tubes, who knows what the actual voltage would be?

I also thought about using silicon diodes. There would be some slight changes in how the amp reacts to the guitar, but not nearly as much as most "tube purest" think there would be. From a visual point of view, using tube rectification looks more in keeping with 1946...lol
