Hello Alan The pictures of the trnsmitter brought back many memories. I built one just like it in about 1955 or 1956 from a Handbook article. There waqs a companion modulator with 807's, also using the economy power supply.
I still have a spot on my finger where I hit the plate choke while changing coils in the final when I forgot to turn off the B+. There was also a tubeless VFO that plugged into the 5763 that kind of drifted around the band. A Heath VFO was put in place to address that problem. Big project for a 16 or 17 year old than.
