I did some more sig tracing and came up with some pics of where the 
trouble seems to be.

Putting a 500 hz sine wave into the mic input, I see a nice sine wave 
until I get to the modulator tubes.

The grid in standby looks close enough but when I go to phone mode it 
gets flaky.

The plates look really flaky in standby but look more normal in phone 
mode but there seems to be a bunch of waves competing for the space.

I posted some pics to http://schmidling.com/mod.jpg

Comments eagerly awaited....
