38-1 code 121A
#22

    Trying to undo the 1946 repairs where #102 on schematics  shows a double electrolytic (can) that was replaced with a single 8uf can on top, then another 8uf underneath. Re-stuffed a double can, and made connections to replace subs. No problem. Part #98 shows a single 18uf can which was replaced with a double 8uf, with the leads tied together to make 16uf. Re-stuffing a can now for that. No problem. They removed that .25uf (#101) along with the 3,000 ohm resistor (#100) So...according to the schematics, the positive side of the 8uf (#102) is connected to the .25 cap, in series with the 3,000 ohm resistor (#100), to the positive side of the 18uf (#98). YES?  I need to know if I'm looking at that 10uf (part of # 102) correctly, as the positive leg appears to be going to ground... Is this chassis ground, or negative bias connected to a terminal strip? On the bakelite cap (#72), there is a 1meg resistor going to a chassis ground lug very near the electrolytic cans that also has part of a wire that was cut off. Am I safe to assume that the positive of the 10uf (#102) was grounded there? These crummy schematics are giving me dyslexia and vertigo. Any help is appreciated.
