Well, great suggestions so far, but DC voltages on a small set 100+ volts positive means either bad measuring equipment or real bad prior alterations. A schematic posted would be really helpful and a few snapshots would also help. So far, not enough to go on IMHO.
this radio works but not properly. i have recapped it and changed resistors #80, # 83, # 86 and replaced cap #31 with 18 mfd.
I have checked most resistors and changed out those that were broken, burned or out of tolerance.
Ok i am starting over. ECG DM-38A Digital multimeter measured to chassis.
osc control tube 6N7G CALLS FOR 260 VDC ON P1 & P2. Actual is 184.5 and 3.3 on K.
6F6G OUTPUT CALLS FOR 250 0N P & 235 on S and 260 on S & 250 on P.
Actuals are 295 & 290 / and / 274 & 264.
6A8G calls for 250 & 85 & (150 0sc plate), actuals are 285.5 & 78,5 and (osc p 135.4)
6K7G (if) calls for P=260, S = 85, & neg 2.5 / actuals are P=295.6, S 79.4, & neg 2.7.
6K7G (rf) calls for 250 & 85 and actuals are 284.5 & 79.5 and neg 2.7
6Q7G calls for 170 and actual is 116.6 on P.
signal is weak unless i hook up 80' of antena and signal is distorted if i was working on a guitar amp i would say it sounds like the pre amp is over driving the output or the neg bias on the outputs is too low making the output fuzzy.

Have you checked the tubes in a tube tester yet? High B+ voltages can be caused by weak tubes, particularly the power output tube.

Those voltages are not really out of line. You must consider that the original voltages were taken on most likely a 5000 ohm/V meter. This will drag down the voltages quite a lot compared to a modern DMM with 1 Megohm/V.
I suggest that your poor reception problem may well be one or more of the antenna coils having an open secondary winding.
