Hi eveyone. I am trying to repace an amp that is used on a S.A.M.I Midway shooting EM game circa 1970. It part number is cm30-2 and is powered by 17vac. This device amplifies audio provide by a sound generator and drives an 8 ohm speaker. The amp (which s missing) has a nine pin connector and has makes 4 connections with the sound generator and 2 with the transformer. The sound generator has no external power so it 2 of the 4 connections must be a power source. Any help in building this or getting a replacment would be greatly appreciated!
