Inside the KLH Model Twenty-One FM Radio

[Captainclock]

I have just recently aquired a KLH Model 21 at Goodwill, mine though was in pretty rough shape as it was missing one of the tone control knobs and the speaker grille cloth was coming detached and it was missing the plugs on the back and the radio had a 60 hz hum coming out of the speaker and no audio from the tuner, I replaced the filter cap and there's still a 60 Hz hum coming out of the speaker and the radio still isn't picking up any stations for some reason. I tried to pull the amplifier board so I could recap it but the tuner board needs to come out as well and the screws holding the tuner board in place are almost stripped out on the heads and I can't get them to budge for the life of me, and I would love to get this radio going again so I can hear what all the fuss is about with these Radios.
