The original post by Joe Walden indicated the audio transformer was 
defective.

Perhaps, he accidentally indicated 6V6s.

This particular radio "may" indeed have been modified by a previous owner.

There is a pretty great deal of information that we have not received.

Therefore, it truly is impossible to take this any further without 
additional input from Joe himself.

We are simply going to be required to wait further input.

I cc'd Joe in this post.

I hope he will indeed chime in and allow us to truly be of assistance.

Sincerely, Regards,
Robert "Bob" Bethman
