I'm thinking if your lucky (well not that lucky) you got 3 bad osc coils. This may account for the high drop across your 4K resistor as the osc tube wouldn't be oscillating (higher screen current).
Or if you are unlucky you may have a bad band switch. If that is the case maybe a terminal is shorting to something else when it's on the SW bands. Or something in the metal part of the bandswitch is shorting to one of the contacts, like where the shaft goes though the wafers.
If it does turn out to be either you may what to consider getting a spare rf deck to swap with this one. I think the ones from a 37 or 38-116 will work in it's place. Ron could help on which ones will work just to be sure.
Seems like I remember BAD posting about a '116 or 690 that just about all of the osc coils where bad.

ps. Henry had or has a 37-116 parts set in the for sale.
