Peavey Butcher on the bench. The lower gain predecessor of the VTM 60/120. The Butcher logo is extremely metal but it actually does more rock-style tones. It’s all good it’s from the mid 80s or so.
Really modular like a lot of Peavey designs seem to be. Main board in the middle is the preamp and phase inverter and has interconnect cables that go to the tone and volume pots. Board behind it in the back is for the output section and the PCB on the left has power supply and bias supply. There is no trimpot for bias supply so you either need to install one or adjust the R52, R53 voltage divider ratio when installing new tubes.
