This looks to be '40s or so vintage. Plug in and it appears to work (I can get a trace), have not done much more than that. The power caps appear to be 2.5uF, 1500V and there are about a dozen of the paper/wax types used in the unit. Should I replace these right off, rather than continuing to fool with it? If so, which ones are the most critical for replacement? I do not have a schematic and limited knowledge, I could not tell you their function by looking at them. As far as calibration, I see a single trim pot, is there a generic approach to calibrating these that someone can explain?
