I wired the referenced kit in July 2019, and it has worked *nearly* flawlessly from the beginning. However, occasionally it will fire up (rectifier, pilot light), but makes no sound. Doesn’t appear the power tubes and preamp tubes are heating up at the filament. This is an intermittent issue - amp has worked today, then stopped. Will likely work again tonight. Rewired filament runs, and tested for continuity - no identifiable issues. Took voltages (when not operating properly) and all are 12-15 volts high at many of the referenced locations on the MojoTone wiring diagram. When operating properly, voltages are nearly exact. Took filament voltages from power xformer, and it appears in the 3-4v range (with respect to ground). My limited understanding is that filament voltages should be 6+. Heaters in 6v6 and preamp tubes never appear to heat up. Not sure if this is related, but I am measuring continuity between the filament connections to the pilot light (pic attached). Is that an issue? Any ideas? Thanks all!
