What I've stated was not guesses or extrapolations. I am very familiar with all of RCA's television development from 1928 thru the TRK sets as I have most of the original manuals, engineer notebooks, schematics, photographs, etc., part of which I have shared with Bob. I have quoted from my original RR-359 service manual and RF alignment engineering supplement and the RR-359B engineering change log. I have provided Bob with the schematics and photographs of his set. All these documents came from the original RCA engineers, DeHaven, Holmes, Carlson, etc.
I am familiar with the specifications, performance and operation of my own RR-359A1 and RR-359B and other prototype sets. I enjoy looking through the Television series books, but there are many deliberate misdirections, like the LO being coupled through the tuning capacitor shaft on the continuous 359 tuner. I'll stick with the original engineering documents and the actual sets
