Emud Model 911 Audio Issues

[DavGoodlin]

I have needed to repeatedly spray down and attempt to "polish and re-spring" the slider switch contacts on the pushbutton deck. Access can be tricky too.

The EMUD 915 I worked on was just like this. The buttons were creating issues with audio, using all the tone/mono/stereo control permutations, including very flimsy tone pots.

First I hit it with DeOxit D5 then CRC 5-56 or contact cleaner leaving no residue, finally DeOxit one or two more times. Don't neglect the lubrication needed on the mechanism/slider. A Korting switch deck needed even more solvent-rinse-spray-repeat.

German designs are so similar across the makes yet parts quality varies. I felt the EMUD was more solidly built than Grundig and Korting.
