Fixed it. I started grounding the grids of the 42 output tubes, no change. Then the 42 second audio, no change. Then the grid cap of the 77 first audio no tone noise. I replaced the 77 first audio, problem fixed. No noise, radio plays and sounds great. Thanks to all that looked at this thread. Mike
