[TenTec] Titan 425 Partial Schematics

[Jim Brown K9YC]

Hi Gang,

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.

http://audiosystemsgroup.com/publish includes links to 8 1/2 x 11 
inch formatted pages of logical portions of the schematic. 

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. 

73,
