Weak/No Volume on FM Band - 51-934
#1

I'm having problems with the volume; sometimes I get no volume when I turn the knob to the FM band and other times only a very low volume and very few FM stations. Any ideas for a solution? When AM band is playing I get really good reception and lots of AM stations. I have sprayed the AM/FM switch but this didn't help. At the rear of the chassis on the left hand side (viewed from the rear) there is a single lead about 4" long and a dual lead same length. I'm assuming these should be connected (soldered)somehow to the 3 terminals on the rear of the cover. I've tried different combinations of hooking them up but I don't get much change in volume. Could someone explain how each of the 3 wires should be connected and if any of the 3 screws should be bridged when in AM or FM.

Thanks for any help;
Andy
