just finished. Built another cool amp. This one is built off of a 5E7 chassis, that I switched to cathode bias, 5U4 and 2x5881. has 3x10" speakers mounted in a homemade cabinet that si roughly tweed bandmaster dims. But.... I also built a PRO cabinet and can basically take this chassis out, and bolt it up. The output transformer is an ALLEN amps 4/8 ohm tapped one, so I have two jacks-one for the 3x10 and one for the single 15". I can swap the thiing over in about 15 minutes.
Came out nice and sounds heavenly. I built a three knob cathode biased 5E5 for my bro tom, and it is unreal. I also built 5f6, 5E3, and 5F1 amps. I have an original 5f6-a bassman, and can honestly say that you don't need the vintage gear and price tag to get the vintage tone. The 5F1 pictured is in a big cabinet with a single 10".
enjoy...
