Ok, I started building it. I bit the bullet and I'm not doing reverb on board. Next I'm building a stand alone reverb for that. I wanted one anyway...
The normal channel is a plexi like preamp, inspired on the Cutthroat Audio Down Brownie.
Power supply nearly finished. Heaters wired...

!It was the only clear schematic I could find. The f#nder ones are blurry ...the mojo one looked ok. It's not uncommon that electrolytics have their negative side connected to ground
LOL

Re: 6G3 build
So how did this turn out? I’m contemplating doing the same 6g3 thing with my new 18 watt Soursound transformer set with a choke and running the el84s.Bieworm wrote: ↑Wed 09/15/21 9:49 pmI'm ashamed to admit .. but Yes.JMPGuitars wrote: ↑Wed 09/15/21 4:47 pmAre you publicly admitting to reading a mojo schematic?!

Re: 6G3 build
Really great amp. But I build these on a 35 watt platform nowadays. I find the 20W really too low in volume. You really need to run these on full volume in a band situation, and then they lack dynamics. The 35W don’t have that problemJason Patrick wrote: ↑Sat 09/23/23 10:43 amSo how did this turn out?

Re: 6G3 build
Wow, that's really poor. Even I didn't make that mistake on my current build! I'll get round to sharing it soon even though it's not an 18W... even if it's just to trigger Josh with more Fendery nonsense!
