Updaqte,
now found some equivalent belts for the panels, a local Gitem (Euronics clone) had some, the audio panel now works, Need to sort the cord system for the cd panel now!
The mute relay now works, having stripped it form the board, discovered the clipping slots in the cover, got it off and cleaned the contacts with cleaner and also a quick swipe with 1200 grit wet and dry paper. Now remounted and works a treat.
The unit is now driving a pair of re ringed S80.2's - well impressed with the sound of them!
Hopefully it'll all be finished tomorrow!
I always try to operate using/following the KISS principle -- Keep it simple stupid!
