I got to seriously looking under the chassis of this thing... someone who knows NOTHING about electronics has worked on it. There are resistors that have been put in parallel that should be in series (voltage divider), missing resistors, a large cap to ground from the grid of the output tube... lots of fun carp. This is going to be a lot of work.
