Looking for specs on this amplifier:

Don't know much at this stage, apart from 4Watts drive (@ 430-480MHz)=
approx. 150W output, draws well over 30A from my poor struggling power
supply. I'm not game to up the drive any further until I know the
specs!

Basically any specs or any info at all would be great, thanks in
advance.


Been a few years, but looks like a PA out of either a MSR2000 or
MSF5000 repeater. In any case, I'd say you were overdriving it with 4
watts, as indicated by the 150 watts out. Its probably a 100 or 110 watt
amplifer. I believe that most Motorola exciters for such amplifiers
put out either 1 watt or possibly 2 watts.
