This amplifier had problems with the CD input.
No or very bad sound, so first thing i thought about.. Maybe the input selector switch ?
Hooked my scope to the output of the amp ( and mediaplayer connected to the CD input ) only 1 channel gave some output signal..
When I was turning around the selector rotorary knob several times, we got some results, 2 channels are working.
Cleaning
So it’s time to clean the selector switch, but then the switch has be removed.
The module & switch have been removed, as you can see it was a little bit dusty..
To get inside the switch, the back must be bended open.
The swaps after they have been used.. a bit dirty..
Final test
Connected a cd-player to the amp, and played some sine wave sounds to test the output, everyhting looks fine.
New switch for my stock
I searched for new switched for this amp, but I couldn’t find them.
