Vintage Receiver Repair – finding a noisy transistor

Troubleshooting and repair of the vintage Pioneer SX-838 receiver that had a noisy transistor. In this video I clean all of the controls, switches, and potentiometers and then because I didn’t have the necessary 2NA725 PNP transistor, I substituted a 2N3906 PNP transistor and it worked great!
