[TenTec] Circuit breaker tripping excessively

[OTAKEBI at aol.com]

Find out what the finals should draw.
Look in your manual.
It should tell you at such a 100w 18 amps.
That is just an example.
If finals are bad you get  like a 20 amp+ draw at say half of rated  output. 
But that would be the same on all bands give or take a few watts and  amps.
If on the bands that don't trip you get full out put and the right draw the  
finals are probably fine.
I would look at a an RF problem, breaker problem or power supply placement  
problem.
Check voltage under load at the inside of the power connector.
I do not think you have a finals problem.
