Also I was wondering if it would be possible to convert my 50 watt to a 100 watt.
I have the extra tube slots, I'm guessing a transformer swap would be the next step.
Let’s forget for a moment about RG-400 cable and C-lator. Let’s make amp sound great without the additional gizmos. Afterwards it will sound fantastic with them as well.
1. Change 100k slope resistor to 68k 2watt. – bit more lower mids, compression and touch sensitivity.
2. add second 250pf capacitor to B2 tube, do not remove B1 250pf !!!
3. Put 3 way switch on master volume with OFF, 33, and 64pf caps.
4. Change RATIO’s (X) feeding 150k resistor to 10k and following 0,005mf cap to 0,01. You will thank me later.
5. Change MID-BOOST’s 390pf cap to 470, sweeter tone.
6. 12 way rotary is a very useful addition.
Good luck
