    1965 Calrad tube tuner (model 202M) signal cutting out

    Hello, all. This Calrad tuner has been working perfectly, but suddenly the sound is cutting in and out and then completely out.

    Pioneer SX-50; Intermittent Power Issues

    My main bedroom stereo is a beautiful 1983 Pioneer SX-50. It sounds incredible, with 50 WPC at 0.007% THD. The only problem with this unit is that it seems to have a dirty power switch, and this problem only occurs when the stereo is "cold", being turned on after a few hours, or the next day...

    Have an SX-636 on the bench. It was acting like an output transistor had shorted, giving me ~20VDC offset across the right channel at one point. Got it to the bench (a couple days later) and checked all the pins on the Power Amplifier board (AWH-034) and the Power Supply board (AWR-060). The...
