[amsat-bb] Mutek Preamps

Hi All. I am looking for any Information on 2 Mutek Preamplifiers I have, One is for 2Mtr operation type GFBA144e and One for 70cms type GLNA 432e. The 2mtr one has a 4pin female connector on the front labeled "CTRL" and 2 "N" type antenna sockets marked "Ant and Tcvr". The 70cms one has a 3pin male socket also labeled "CTRL" and the same "N" type sockets. Any information regarding where I might purchase these connectors and any other Info would be very much appreciated. I have emailed Mutek a number of times over the last 2 months but no response from them to date, their Web site also seems to be a little out dated. Many thanks in advance.
