Hi All, I've searched the archives & website for info on this Amp and can't find anything. It's sort of similar to the N1275A or the N1248A convert-a-com amps but for a Motorcycle (I was told). It looks like the back end of a MoCom 70 heat sink. I need more specific schematic or manual info so I can integrate it into the repeater keying control logic. The Amp is working fine on 147 MHz, keys up on RF input and makes rated output. I want to use it in repeater service at reduced (~40 Watts) output, possibly with a small fan for cooling, as needed. Anyone have any history/info using this Amp?
Model N1254A, 150.8 to 162.0 MHz, Mfg Aug 1977. Max input 7 Watts, Output 60 Watts. FCC # CC 3303. Power Amp board TLD8922A uses M9622/23/24 & two M9625's for final transistors. Output directional coupler/power monitor board, TLD8922A. Input attenuator (-3 dB) & RF sense keying board, NLD7141A. Input/Output bypass relays are 23C84103B01. Any info, links, etc. much appreciated. Tnx, & 73's George
