Scan of photocopy with some fading at edge of schematic; otherwise okay. I scanned at highest resolution possible (600 dpi) to compensate for photocopy condition.
Hallicrafters HT-20 transmitter "Run 1" 100 w., 1.7 - 30 Mc. continuous; 4D32 modulated by pr. 807; 5R4 rectifier
20 pages 11 Mb http://home.fnal.gov/~atkinson/HT20opmanual.pdf
Sorry for the wasted bandwidth: I realized that in my senile condition I had downloaded and printed out the HT-20 manual from K4OZY's manual website the year before last. Then, having completely forgotten all that, I dug my copy out thinking it had come with my rig when I bought it, so I scanned it and put it up. So, what I had here was a scan of a printout of someone else's scan. Not very good at all! So in the interests of quality improvement, I'm pulling mine down and giving the K4OZY url to his FB Hallicrafters manuals, and credit where it is deserved:http://jptronics.org/radios/Hallicrafters/manuals.html
If I could, I'd delete this whole thread but I don't see a way to do that. I apologize for the mistake.
