Greetings! First-time Poster, and certainly enjoy the Site! Picked up a Lafayette LR-810 for my Test Bench. Found a shorted cap, but need a schematic to continue. It receives OK, but only MONO. The meter doesn't move (no matter how much signal comes in, even -50 dBm from a calibrated sig gen!). Also, the Stereo Light doesn't illuminate. Thinking the IF Amp IC might be bad. Thanks in advance! -- RadioBob
