Good evening all,
I am restoring this car radio, and I encounter a strange problem. The second IF transformer resonates at approx 650kHz, instead of the 455 kHz.
I opened the transformer, and I discovered a series resistor, marked 25kOhm; but measured 35.8 kOhm.
But i suspect the trimming capacitors (mica). But I wonder how it can detune the circuits so much, from 455 kHz to approx 650 kHz.
Who can help?
Best regards
