Turn on the DRPA today and give it some level. The right channel volume was very low, then volume would increase, then cut out and repeat. Ruled out everything else in the signal chain, it is the DRPA. The left channel did not have this problem, however it did have a very slight distortion to it. I was able to limp through all 4 bands running in mono. Outlets were wired correctly but voltage was high, 127ish. I don't think that was the issue as I was able to locate one outlet that was supplying 120 volts and the problem did not change. Any ideas what could be up with this? It is 7 years old and has never been mistreated. Thanks.
