Hi Bob,
I think you have the schematic from this site:
Crosley Trirdyn (crosleyradios.com)
The schematic may be drawin by someone other than Crosley. The pictorial schematic is likely the correct one. I think that the schematic in the above website is incorrect for the headphone jack. The frame is connected to +90V. The tip contact should be connected to the RF Output transformer primary. The switch contact should connect to the AF interstage transformer primary.
The following doc is from the Nostalgia Air site. I think that the hand drawing for the Tridyne from the N/A site is correct. However, look at the 5-38 diagram 0n the same page. The plate of the 2nd AF is connected directly to B+, so that diagram can't be correct. We can't contact the person who drew the diagram at Rider unless someone knows how to contact Heaven.
I have to apologize, I can be obtuse in my entries. Back in my Field Engineer days, I had to write a monthly technical report. These were hand written as this was the 1980s before affordable laptop computers, and I did not have a typewriter. My reports were hand written and then sent to the district sec- Oops, admin assistant. I may have driven her to drink. I would get a call from my boss stating that Donna is trying to type my report but could not do so because someone borrowed the Rosetta Stone. He would then ask how I got through 11 years of Catholic educations and earned a Bachelor of Science degree from college with that handwriting.
