Amps are not a purely nuts and bolts thing to troubleshoot.


You have to have the equipment necessary to run signals through them and examine the output...lots of cash.  Otherwise you will be outputting a dirty signal or cook the amp components.


You can get hurt really badly 'playing' around with amps if you don't understand what you are poking at.


You can get hurt slowly if you are exposing yourself to high levels of RF radiation if you don't know what you are doing.


I've been looking into this for a long while and it is nowhere near as simple as you may think. They are simply not a weekender bench project with a screwdriver, soldering iron and a VOM.  The more I read, the more this becomes obvious.


And one last bit, RF amps are RF amps are RF amps in principle.  There are different approaches to the circuit designs, but what band they wind up on is the simplest part of the equation to fix and just a few components here and there.  So to add back to the original question, by asking for 11m specific amp instructions...it really shows you don't know what you're asking right now, and my advice would be to find someone who is qualified to work on it with/for you.
