N1275A UHF Brick Amp

Postby N8ORJ » Fri Jul 20, 2007 5:38 pm

Does anyone have the docs for the Motorola N1275A UHF Amp? I have one in the 403-420 range and want to move it into the ham band. I have moved the internal trimmer cap and had some success but it will not move then freq range far enough. I have found some info on it's VHF brother, the N1274A that indicates there are some frequency specific resistors and cap in the LC network. I suspect there is a similar design in the UHF version. While I am at it, if anyone has a full set of docs for the VHF 1274, that might come in handy also

Thanks
Jim
