Has anybody ever experienced a 9090DB completely losing FM signal? The voltages seem to be fine on the F-2549 tuner board, and the F-2619 PS voltage is set at 12.5 (was at 13.55v). I was just listening to the radio and heard the signal begin to cut out. The signal meter was dropping, and the tune meter swayed back and forth. Then it just dropped out completely. The BCE voltages at TR01 thru 04 seem to be fine. I am beginning to suspect something in the front end gave out and would really like to avoid going there. But if I must, I'll dive into it.
