I went back and looked at that web article, and obviously it's an earlier version of the transmitter. I was a little confused when you said "output transistors" (plural), and "class C operation". My kit has only one output transistor, the hot-runner I described earlier. Schematic attached. I wonder if the push-pull version worked better, and why the change (performance or cost?).
I probably confused some people talking about the 9V power regulator too. Something apparently they added later, as it's not in the web article either. They recommend a 12-15V supply (mine is 13.8V), the 7808 VR1 flattens it very nicely to 9V.
The oscillator and audio/video amps look unchanged. I guess I don't follow how the audio oscillator at 4.5 Mhz adds in, but I guess that's the signal that affects the shape of the sine wave at Q5's output, so I guess that's ok and the harmonics are expected. I don't think they're filtered well though, as like I said, tuning channel 3 also pretty clearly tunes channel 8 (the 3X harmonic).
Anyway, hope this schematic clears up what I was describing. I still can't see the people at Ramsey being proud of this product. Maybe the TV-7 or 8 or 9 will get it right someday... Not there yet, IMHO.
