[QUOTE="Neo__04, post: 223348, member: 4733"] Need to bump an old thread. I have been working on getting this amp going recently and am having some problems. I have built it exactly the same as the original parts list and the wiring diagram. I have a problem with interference. With a gme spk07 speaker plugged straight into the detector, it works fine, nice and clear. When i plug in the amplifier module and a different gme spk07 wired to suit, i get an interference humm which is quite loud. I can hear the signal in the background, but there is some interference that it masking the audio. I have tried the amplifier board with a 50k pot for volume originally, though there might have been a problem with the amp board, so i ordered more and got some of the boards with the volume pot on board. Same problem. Im sure im doing something stupid. But ive got no idea what. Can someone confirm the wiring for the plug that goes into the gpx5000 battery? im using a stereo plug. Thanks heaps.
