View Full Version : galaxy 959 squeal

08-17-2014, 09:31 AM
Howdy folks. I just did the 10kc mod on my 959 and now have to run the mic gain halfway when the amp is on or it squeals. The switch works, center=normal, left=10k down but right should be 10k up and does nothing i.e. normal channels. Do you think I screwed up the mod, should take it out, try another switch or posibley the location of the sw? Put it above the final between final and echo knob. Maybe its causeing interference. I don't know. Any help will be appreciated. 73s

My first thought:
Sounds like it could a feedback issue between the mike
and the audio section. Why? because the mike gain setting
affects it.

Try and see if a change in physical position, of the relationship of the
mike and speaker makes a difference. Mover the mike away further,
at a different place vertically or an angle.

If that does nothing then there are other problems.
