Cool looking amp and I'm thinking very rare so it might be hard to get the exact knob. You might have to get the knob 3D printed or consider changing all of them to something similar.

Yes I owned one of these years ago and the advice at the time was to not use the standby switch. I, in fact blew two rectifier valves before I discovered this. The amp naturally heats up to operating temeprature if you just turn it on. It takes 15 to 20 seconds or so for the sound to come on. I also remember the amp chewing up a few 12ax7s in the reverb slots. I would recomend buying from a tube seller who has tested their tubes and offer a warrantry on faulty ones like Eurotubes for example. All the preamp slots do call for 12ax7s so go with those.

I stopped using the standby switch on mine (because it was eating rectifier tubes) and just let the amp warm up naturally and just powered off to shut down. It didn't seem to cause me any problems after that. Although it can sound pretty good, the main issue with the amp is it weighs a lot but doesn't put out a lot of volume for its hefty form factor. The Triggerman 60 DSP 1x12 is much loader and it's solid state but can easliy keep up with a drummer.

Use the FX loop send return for the best sound.

Bought one of these new in 2009 and still use it today. Amazing solid state amp. It's loud enough to gig with and has a lot of tonal and recording capabilities.
