Amp Garage Registration
I registered on ampgarage.com 5 days ago and still haven't been approved as a user. I answered their one question correctly. Does anyone know what's going on there?

KiCad users?
Has anyone out there had experience using KiCad? I want to create a schematic that I can easily modify and share. Are there better tools? And is it good for both tube and solid state components?

MOSFET output stage question
For my next guitar amp build I'd like to save some weight by using a MOSFET output stage in place of the output transformer and output tube and use a smaller power transformer as well. It would be a hybrid amp with a tube preamp section. Does anyone have any experience with this?

Vibrochamp + reverb project
I just finished final wiring of my from-scratch 5F1 mod. I was inspired by Uncle Doug's Vibrochamp project and by an earlier project in which he built a slide-in chassis. I was also very influenced by Erin Elam's (Youtube: elams1894) exquisite builds. This build uses solid state rectification to save a little room, but you can see it's still extremely cramped. Ran shielded wire where I could. High and low inputs sum at V1A (1/2 12AY7), then gain control to V1B (other 1/2), then tone stack to the 3rd gain stage at V3A (1/2 5751), then to output tube (6L6) and 12" speaker. V3B is the tremolo oscillator. V2 (12DW7) is reverb driver and recovery. Transformerless reverb. Also: choke, elevated heater, bias board and NFB. This weekend I power on and test voltages. If it doesn't blow up. Will post results.
