JTM45/2204 combo with reverb and FX loop WORKS!!
« on: December 05, 2022, 11:54:44 am »
Well,

I completed the amp over the weekend, and it works GREAT!! (so far...) Both front ends, the FX, reverb, everything.  Sure, I had a couple of quick debugs to do for "mistakes", but I found them quick.

On to making the head cabinet.

Congrats on your successful completion. That's a very cool amp! I see a lot of nice options there. Can you post the schematic?
I love tubes

Nice schematics. How are you liking the two preamps? Any comments about the sounds? I'm interested (thanks I just built two amps  :help:  ).

Up above I realized that the note on the PS schematic wasn't updated.  The voltages on the schematics are with ALL tubes installed.

The sound is great, I get both/either with the flip of a switch.  BTW, I fixed the note on the PS schematic regarding the voltages, make sure you get the new one.

Thanks, I actually did download them earlier so I'll make sure to download the updated one.
