Been busy with the stereo the past couple days, to keep my mind off everything.
Power amplifier board got a full recap. One channel.
Got 4 caps tucked away down the back that look hard to get to also. They got put on the “another day” list.
Nice and even!
Next up, the tuner board. Got it unscrewed and gently lifted up.
Access wasn’t very good. Ended up having to check solder joints with a mirror.
That went back in, all very well. FM and AM reception improved significantly, but is still poor.
Had an extra pair of hands for this one. Thanks, honey. More stations pull in stereo now.
Can get some deflection on the meter with a strong local AM station also.
Moved on to the power supply board. Got the thing unclipped, and again with minimal access due to wires.
41 years of product development, things have become more compact.
Some of the caps had gone bad, a couple had legs that had corroded away to nothing.
That had made a mess on the board.
Cleaned it up with Q-tip and isopropyl alcohol.
Refitted everything once complete. Looks good.
Powered it up, and there’s a bad smell and one of the fuses pop. Oh dear. One of the caps has gone off like a popcorn kernel.
Pulled it off the board, and sure enough, the markings on the board are wrong for + -. Replaced it with a cap of the same type destined for the protection board.
All done. Played ok for a while, switched off. More to follow.
