Its all about the Music
So I have this one on the bench today, parts order finally arrived.
Faults are Right Front VU meter not working....FM Stereo Light not illuminating....huge DC offset in rear amplifiers causing it to stay in protection.
Usual intermittent switches and the likes, the Low and High pass filters are causing some issues as well...
So there's a bit to do...
So I thought I'd start at the power amps and work back from there...So I fired it up and the rear amps were suddenly fine....
So I pulled the power-amp module out of the unit (so much easier than anything I encountered on the 9001 I repaired) and to my horror, but relief I could see the problem....
One of the Main Filter caps has started leaking, and its leaked all over the rear power-amp circuit.
So there was a lot of cleaning.
Few pics showing the start of the journey through this mighty quad receiver, I actually quite like the build of this one...
