I have an AU-519 of which I am very fond, but has been in its box for over a decade.
It developed the lost channel syndrome, where a channel would crackly away and dissappear, maybe so that it could still be heard very very quietly, or maybe not working at all. Sometimes both channels would go out.
Fiddling with the volume nob (generally cranking it up sharply) sometimes brings it all back. But it would eventually fizzle away again. This tactic worked less and less.
If I open the box up and dust things off with sprayer or toothbrush, that usually fixes it for a little while. I sent it to pros who would fix it (clean it) but it would only last a while. So I gave up.
I really want to get it working again. I am going to get some of that Deoxit as per other threads on this board. But I have two questions:
(1) Should I use the Deoxit progold5 or pro100?
(2) are there any other tips I should know, like: "never touch the red button", or "never unscrew the widgetthingy"?
Thanks! I got some old JBL L100s currently doing duty as shelves, and they have been chomping at the bit to play music again.
