I'd like to check the bias of my Krankenstein and adjust it.
I have a feeling tubes are set way too hot, although this amp has all kind of weird problems. Color drastically changes when I open the volume (and this is not the zero to 1 sounds different problem, on high volumes the tone still changes drastically)
It has loads of other problems too, eq doesn't work like it should, I can barely turn it open, same for presence control, if I set it on 2 it sounds like it's on 10.
Only problem is it's a prototype and I've never done biasing, does anyone have an idea where there's a pot to change plate voltage? I'm pretty sure it's not a fixed bias in this amp.
By the way, it's the first 100 watt version.
Here are some pictures:
