Hello All
Well, found the 1400 ohm portion (between lugs 1&2 )of the long power resistor to be open, as well as resistor 17. Replaced 17 and now have plate voltage on the detector. Reading through other questions/answers, I read that putting in a 10 watt 1500 ohm resistor in place of the open portion should work. Installed it and the radio now plays!! BUT, I still need to recap, and align, there is some howling etc. My immediate concern though is the 10 watt 1500 ohm resistor. I have the radio on now about 1/2 hr, and that resistor is hot! Can't keep my fingers on it. Question with that....
Should it run that hot? Can I get a heak sink for it? If I put it in permanantly, can I snug it against the chassis so the chassis acts like a heat sink? Voltage between lugs 1&2 is 55vdc. Lug 1 to ground 47VDC lug 2 to ground -7.5vdc. THANKS!!!
