In this episode of VINTAGE AUDIO REPAIR I take a look at an early 70's Pioneer SX-9000 stereo receiver. This receiver was brought to me with the complaint of no sound on any input, AM-FM-AUX-PHONO all dead. I troubleshoot the distribution power supply and determine that there is a faulty regulator transistor. Once the transistor is replaced the unit is back in operation once again.
