David, I found this tip on another site, may help, replace zener 6408 8.2
volt, replace 33 Ohm resistor next to
stereo decoder chip on B+ line, and of course the STK4392 which you have
already changed, the tip did not
give the "R" designation for the 33 Ohm resistor so I don`t know it`s
location, all I could find, hth, Larry E
