phlogiston posted a link to a 91B schematic above. I already downloaded it. I'd have to bone up on wiring diagrams just to be able to read it. What I'm looking for, for now, is a spatial diagram or layout or drawing or labeled photograph of a chassis so I can identify what and where everything is located. The schematic doesn't really do that (except for the tubes, shown and labeled as they are arrayed on the chassis in a little drawing on the bottom of the schematic). For example, when you say I will uproot the low-wattage resistors, I find myself wondering where they are and what I will be doing and at what step in the process that uproots them. Pulling on someting, I am guessing, probably a wire. Heh.

I am off to the library... Too many questions, and I see that this place is really for the more experienced. That's totally understandable. I still don't even know if I'm supposed to take the chassis out of the cabinet, and if so, how. So if I'm going to do this (still an if) I feel like I'm a long way from a voltage meter...

Thanks again.
