Titan 425 Partial Schematic

From the Ten-Tec Reflector January 24, 2008

I now own three of these vintage amps, and they require frequent maintenance to keep them running. Ten Tec's printed schematics are spread across a dozen sheets, and are difficult to follow. This partial schematic is my attempt to put all of the switching, keying, control circuitry, and power supply on a single sheet of paper to make troubleshooting easier. This pdf should print on an 11 x 17 inch sheet of paper, and can be viewed at any magnification on your computer screen. Note that this schematic does NOT include details of the RF signal chain, but which is much easier to follow in the printed manual.


Sharing of these links is encouraged, and corrections/comments will be appreciated. Please do NOT distribute the pdf files themselves, so that I can correct them as needed.
