Check out http://www.repeater-builder.com/ge/lbi-master-list.html do a control F and type in the part numbers
They sound like typical lower powered amps for base stations (as opposed to continuous duty repeaters. They are designed to mount in a base housing where any of the amps go, they should have one PL-259 on a angled bracket and room for another one just above it, Hope this helps Andy W6AMS From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of skipp025 Sent: Sunday, September 13, 2009 8:44 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] GE LB VHF RF Amplifier Drive Level? basic specs? On the way home from yesterdays Lincoln, CA. Ham Swap I noticed a bunch of surplus GE Radio Gear just "up and jumped into the back of the truck". Two of the hitch-hiking items were GE VHF RF Amplifiers, looking a lot like a GE Master II Mobile decks factory mounted into a frame used in a base/repeater application. The RF Decks appear to be VHF Low Band units with the printed part numbers of PL19B219688G6 REV on each. The final output devices are 4 labeled C4104P1 transistors as is the single driver. The remaining first input device is a transistor labeled C6965P1. So... can anyone tell me the basics about this PA Model? Drive Level? Realistic Output Level? The output of the PA goes toward a covered T/R Relay section in the chassis/frame corner where I see connections for a receiver port. Is the T/R Relay normally powered/energized with each transmission to route the RF Amplifier to the Antenna (output) Port? All the RF Connections appear to be the RCA type... Unlike Motorola RF Amplifiers... I'm not seeing an RF Power Stage Control Voltage line/wire/connection point from/on the chassis? The two chassis that came home with me look to be real cookers for something on low band... if I can get them to work. Thank you in advance for your replies... cheers, skipp
