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....
