New here, an 89B I'm repairing
12-01-2014, 03:13 PM
Finally got back to the 89B after a long hiatus, and I got both the oscillator and antenna coil primaries rewound successfully. I fired it up again, and success! I picked up some local stations quite well. However, it drops out tuning below 1100 KHz. It doesn't appear the tuner plates are touching. Would changing the 36 cathode resistor to 10K help the oscillator keep oscillating? It seems that it just stops oscillating below that point.
