On the inside can be some corrosion, but that's just an idea to explain some hum.The solder joints are really thick too.
Remember to adjust after the new outputs.after that it's the output transistors
They need to be clean, use some WD40 to remove the old paste... just a small, thin well spread amount will do the job, too much is not good.should the legs for the transistors be clean or covered in thermal compound?
How was the offset previously?Thoughts?
Very touchy and difficult to adjust but I had it within 5mv of 0mv before the recap.How was the offset previously?
Just as clarification, witch unit is in protection mode?Right when I think I'm finished too haha.
The AU719 is in protection mode again. The 8080 is working beautifully!Just as clarification, witch unit is in protection mode?
Phew!!... Worry not, It looks that the protection circuit is doing his job. That's usually the drill with Sansui, they will have some issues until is properly reconditioned (like you did with your 8080).The AU719 is in protection mode again
