Tubelab sse cathode feedback. The Tubelab SSE Assembly Manual details the assembly of the PC board. This helps linearize the output stage and will control the speaker better. I am wiring as per image attached, with cathode feedback not used. This puts the caps directly across the cathode resistors. After a few of these tests I decided to connect the best low cost transformer (Edcor XSE15-8-5K) up to the best low cost sweep tube (6AV5) and drive them with a Tubelab SE board, power the whole thing with a bench supply, and apply a little cathode feedback to help out the smallish transformer. The mode (Triode / UL) switch, the Cathode feedback switch, the standby switch, and the rectifier switch are optional, and should be hard wired into the desired position if they are not used. After playing with it this weekend, I added the switch panel. The amp runs with a B+ of around 450 volts using 5K ohm output transformers and can be run in triode or ultralinear mode. If unsure of your particular OPT's try wiring the secondaries each way (swap the two secondary wires, leave the primary alone).
