I've trying to figure out why the stereo beacon won't light on my recapped Kenwood KT 6007. The beacon didn't work before the recapped.. The only voltage I don't have is on the collector of Qc13 (MPX PRE amp board). The tuner plays fine . The original Qc12 &Qc13 diode tested good (replaced anyway ,didn't work) . Qc4, Qc5 &Qc15 all diode tested good . I also notice that my unit is not wired like the schematic . The Auto FM is not wired at all. It seems the when the mono button is pushed in it grounds pin 8 of the HA1156 to ground which puts the chip into mono . I'll see if I can post the schematic ,my file is to large .
