I have tried turning off the lights in the shop and the router. No change. I will also say that even in the area of the buzz a strong station will come in. I have not changed any of the tubes since they all check good and I don't have some of them extra to try. Radio performance otherwise is quite good. I may put it back in the cabinet and call it done until I get a signal generator to check the alighment.
