    Predator 400 linear amplifier

    Does anyone have a schematic for this 4 x MRF455 unit. Also is it a 10 meter linear. Swr is 1.2 with my GALAXY 99v but jumps to 3.7 with the 400 on high. I have tried a White Tornado 225 in the same vehicle with swr 1.5 on high.

    over on cbtricks there is a lot of manuals there. here is the link for them.just start going through the different bands until you find one like what you have. most amps are duplicates of each other.
