Skipp. The 19B219688G6 is a heat sink assembly that is common to four PA assemblies and PA boards:
19C321295G5 and 19D417927G1, for 25-30 MHz 19C321295G6 and 19D417927G2. for 30-36 MHz 19C321295G7 and 19D417927G3. for 36-42 MHz 19C321295G8 and 19D417927G4, for 42-50 MHz The PA is rated at 100 watts, and all use the same transistors. I may be able to get more information, once I know which board you have. 73, Eric Lemmon WB6FLY -----Original Message----- 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
