I’m very happy to report that thanks to a NOS pair of Eimac 4-125A modulator tubes from Antique Electronic Supply, my T-368C is back on the air for the first time since I got it! I’ll still have plenty of tinkering to enjoy on it, and plenty of work integrating it into a full system with my R-390A receiver. I’m also happy that my antenna BALUN didn’t burst into flame upon encountering the hefty output of this small monster of a transmitter.
I plan to experiment with outboard audio processing to see if I can improve the unit’s classic military audio sound, which is intelligible but not very clean-sounding. I am interested in experimenting with that stuff, but I would prefer to avoid modifying the transmitter’s innards as some other T-368 fans have done. So, my goal will be to see how much I can improve the stock audio using only outboard equipment. I’ll post any favorable results.
