6G3 build

Post by Bieworm »

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...

I'm ashamed to admit .. but Yes. πŸ˜„!
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 groundπŸ˜‰ LOL

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.

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 problem
