First of all, I'm loving the sounds I get out of this amp. It sounds great, it's quiet and I'm just ecstatic at the sustain and compression. I built the BootHill kit and have a cab from Mojotone, a 12a125a 30 watt speaker, JJ tubes. The build went smoothly and the amp fired up without a problem (except I did screw up by getting a little solder into one of the preamp sockets, which had to be fixed before getting a tube to go in). I spent a lot of time considering how to approach each step before actually executing. I feel my decision to do all the turret board wiring on the top of the board was a good one. One thing i do regret is not locktiting all the mechanical, non-electrical screws and nuts and so forth. Hoping vibrations won't loosen things up. I did a couple mods from the robinette website (https://robrobinette.com/5e3_Modifications.htm); specifically, a resistor across the standby switch to eliminate pop, and the "backup" diodes going into the rectifier tube. A friend whose electronic knowledge I greatly respect suggested I could also feed all the filaments with DC by adding diodes. Has anyone else done this? I didn't see such a mod on the robinette page but should one be there? If so, anything to watch out for? I wasn't sure if it would simply need 1 diode in front of each line going from the pt to the filaments and light, or if it would need 4 diodes in a bridge. Anyone know a reason I shouldn't consider this? Next I'll probably strip the whole amp and finish the cab with some shellac and polyurethane. I've been vacillating on whether to finish it or just leave it raw.
