As Arte Johnson used to say about 200 years ago...
Good work. But I must point out one error in your post...
Conversion to a 77 tube was not my idea. It was a factory change made by Philco during production of the Model 89, in September 1934 during production of the 1935 model line. I cannot take any credit for that as Philco's engineers put that into production.

Scroll down to September 1, 1934: Code 123, Run 14.
I have never changed any 19 or 89 sets from a 36 to a 77.
The "Super" mod (changing to a 6A7 tube and changing the oscillator circuit to allow use of a 6A7) was my idea.
