pioneer sx1500td blowing fuse
#64

I went ahead and waited for the 2 new output transistors from mouser.
Installed them and put the main ampl. back in the unit.
It still had the problem. Drawing heavy current. GRRR! I almost just quit on the thing but I'm hard headed.
Took amp back out, took out OP transistors. Rechecked them they are good, and everything on the board again. This time I changed VR3 & VR4 50 ohm pots.
Hooked it up out of unit. I know have AM playing loud and clear and amp. guage is reading .1amp.So thats good but I have no FM, on mono or stereo, the signal meters work . Just barely audible hum from speakers when on FM settings.
I feel I'm getting closer to fixing this and plan to reinstall the main amp. then trouble shoot for the no FM problem.
What should I start with for the no FM? Your help really needed. Thanks
