[Motorola] Manual/Information wanted

[n_griggs at bellsouth.net]

I have recently aquired a 60 watt VHF mobile amplifier.  The model number is model N1254A and the nameplate says it covers 150.8 to 162.0 mHz.  7 watts in gives 60 watts out.  I found the part number for the installation manual through the Motorola Business website - 6881102C63.  Does anyone have a copy of this manual and/or a schematic/other specs for this amp?  There is a square metal 'box' inside with two RCA connectors on the top.  This is inline between the output of the amp and the coaxial relay on the output connector.  I haven't opened it yet but think it may be a filter of some sort.  From the looks of the amplifier board, it appears to be wideband and the frequency range may be limited by the output filter. Any other information is appreciated.  Thanks in advance....
