Mocked up and ready to start modeling the chassis for a 2-6V6 power / Matchless Spitfire preamp / 1-tube reverb combo. The PT is from an old radio (if I remember correctly). It is another 110v so will need a bucking transformer to keep voltages where they need to be. At 110VAC input, it puts out 330-0-330VAC and normal voltage at the heaters. The choke, impedance selector switch and tube sockets come from a Hammond AO-15 amp. The PT is from a mystery push-pull 6V6 power amp, tests at 8K primary and has 4, 8, and 16 ohm secondary taps. I’ll be using a reverb tank harvested from a Hammond organ but will need to purchase a reverb transformer in order to complete the project. I’ll be carving the chassis out of the 2” X 5”, 1/8” wall tubing shown in the mock-up. I’ll try to be more diligent at photo documentation of this process. The first one I did this way turned out great. https://www.tdpri.com/threads/junk-pile-build-the-“champlifire”.964902/ Wish me luck!
