Re: [TenTec] Ten-Tec 411 Centaur Amp Problem S-O-L-V-E-D

Good afternoon,

The problem seems to have been the input filter, exactly why I have not 
figured out.  I pulled that filter and put a jumper in its place and "bingo" 
no SWR on 40 (or the other bands) and full power out as it should.
The "PI" filter (actually is more complicated than a PI - it has a third 
inductor and Capacitor to ground tapped from the middle of the inductor part 
of the PI.   I imagine that part is designed to pull certain higher 
frequencies to ground.
Now I want to modify it so that it will OP on 10 and 12 Meters.  Has anyone 
gone through this MOD?
