Welp, I recently did an amp re-build and when I went to test it for the first time, I'm getting local radio coming through the speakers. Stronger when the vibrato is turned up (using the exterior pot and the thumbwheel trim pot on the board). If I turn up the vibrato to its fullest, the radio signal is *very* strong. But even at lowest volume and lowest vibrato, the radio signal is present coming through the internal speakers. I have not tried using the aux out to see if it still happens (I don't currently have an amp to use).
Anyone had anything like this? Did I install my grounds incorrectly perhaps? I read several times that to reduce hum you should find and eliminate any 'ground loops' and that the stock Wurlitzer ground scheme is not very good, but when I look to find exactly *how* to find and eliminate ground loops, the info is from electrical engineers and it's all jargon...
Thanks!
