You were absolutely right, Mondial. That was it. This was about the worst schematic for errors I'd ever seen. Not just showing all the e-caps going to ground, which clearly doesn't work (I had them like that and had the non-controllable buzz), but showing the tubes in the wrong places in the chassis! To further complicate things, as found the grid cap wires were not going to the correct tubes either! This was the first radio I actually had to trace out the circuit to find which grid cap went where! So the set is playing now, but I'm not out of the woods yet. I'm dealing with an intermittent volume drop / bad connection on one of the 6D6 tube sockets that seems to be related to the goat shield. So I have that to sort through yet but at least the buzz is gone and it's receiving stations!    Thanks to all for their help and knowledge
