How the Fender 5E3 Deluxe Works


This started out as someone on TDPRI asking for some enlightenment on what the various components do in a 5E3… before I realized it I had described nearly every component! Here it has been consolidated and reordered, along with a copy of the Weber 5E3 Deluxe layout that was used as reference.

LBA Octal Head

Octal Front

I had been wanting to try an octal preamp for a while, so I figured 2011 would be a good time to build one. This amp has gone through about a dozen revisions with tons of experimentation along the way. After 2 years without major modification, I ditched the cascode and moonlight tone stack on Channel 2 in favor of a two-stage design.

5.1 Tube Home Theater – Main Channels


Building an all-tube-powered 5.1 channel surround sound home theater system is probably the most ambitious project I have attempted. My goal is to build a surround sound home theater system using all tube amps, and to do it without bankrupting myself in the process. To pull this off I had to set a few guidelines that would keep this project under control:
