An Update!

I finished doing the conversion this weekend. I recapped it, replaced a few things that were out of tolerance, added a fuse, an on/off switch, and a pilot lamp. Hooked it up to the speaker...

It sounded pretty decent. I found it a bit "spanky" if that makes sense in the mids/treble range. I then built a tone stack like this:




It lets me tweak the tone so that I like it, but the loss of input signal is killing me! It can't really drive the speaker well, and it's much quieter than it should be.

As you can see from the schematic I posted previously, it only has one 12ax7 which is preamp, and phase inverter. I'm thinking it needs more gain to drive the 6V6s. I did the math, and adding another preamp tube would have the PT running on the ragged edge of saturation, and I don't want to risk my 60 year old transformer.

The current solution I'm working on is this: https://www.modkitsdiy.com/pedal/persuader_deluxe

Does anyone else have any good suggestions or ideas that aren't ridiculously expensive? I'm looking to get a clean bump in gain, and I'd also like to be able to drive the tubes into distortion which I can't do currently. The pedal would do both I think, but I'm open to other ideas to try.
