For all you guys experiencing power problems, preamp tube problems, effect loop problems and overheating on their Budda amps, I discovered doing a retube that the tube access holes in the aluminum chassis are waaaay to close tolerance and in my case was not allowing the tubes to fully seat in the sockets. This problem caused two of my preamp tubes to not function properly, not light up and sometimes creating a short in the power supply. I do not know how the holes can be enlarged withoit a total disassemble of the pcb. Needless to say I am ticked beyond belief. No wonder they went out of business.
