I've got a Coronado Model 43-8245. Two resistors have burnt markings, and I wonder if they are the cause of the radio playing so poorly. I've replaced all electrolytics and paper caps. Radio receives, but reception and sound is very weak with lots of distortion when the vol. cont. is turned. Sprayed out pot already, and cleaned variable condenser.
Both resistors go to pin #1 of the 50C5 tube. One comes from pin 7 of the 35W4 ( a hefty one...a 1 watter?) The other comes from pin #1 of the 35W4 (a smaller 1/4W?). Anyone out there know the original values??

Hi Tjay, I've emailed the schematics for your Coronado (Gamble Skogmo). The resistors concerned are the output cathode bias resistors and they could cause the symptoms mentioned. Since you've replaced the caps they're not likely to be the problem. If you need any more help please just ask. Good Luck, Don Black.
