I made this amp last year and it has been my main shop amp, but recently it has been supplanted by the Budgie SE amp. Today I'm tearing it apart to be a test bed for a new 300B amp based on the get*set*go. After that project is completed, I plan to revert this amp to a Clementine, but with 1625 tubes.

Sometime last winter I modded it from a stock ULtra build, to a 6BG6 tube. The picture below shows the cuts and jumpers. I basically cut the trace going to pin 8 and soldered the UL wire directly there. I then ran a jumper wire to the cathode bias resistors. I used bare wire so that I could clip a DMM on it easily to check the bias. The blue plate wire I ran directly to the plate cap.
