OK. I cleaned the amp. The Murphy Oil Soap seems to work really well, as it gets the dirt and leaves kind of a nice light sheen (there is a little vegetable oil in the soap). Vinyl is like new.
no brown stuff...
Somewhat better control panel...
I found that rubbing the rust only caused the rust particles to loosen and scratch the chrome a bit. I think I'll just live with what surface rust exists. It's old, after all.
