I've been doing work on a Sansui 5000a recently on and off. The issue it's had since the day it ended up on my bench is 38 volts DC on both speaker channels. I tested the transistors on both drivers and none test as shorted, and I went ahead and replaced all 4 output transistors with ON Semi's MJ15024G. A bit overkill for the application, but I got a bunch on a good deal. None of the original outputs test as shorted in anyway. Yes. Before the question is asked, this 5000a was lucky and has the updated F-6013 drivers. I'm sure as old as this unit is, it's cap coupled. So I figured I would post here and see what others thought. I'm wondering if, since both channels are doing it, that the main filter caps are probably long gone? At least that's my hope. The post is here for exactly; What else should I be looking at besides a recap of the drivers, replacement of all the big filter caps, and a recap of the power supply? Sansui uses higher values then Marantz and Pioneer which is what I primarily fix. So, I don't have any filter caps on-hand. I have to order them all out. Two are 1500uf at 80V the other two are 2200uf at 90V. Everything I own is 63V or less.
