I have an old Hallicrafters Transceiver that uses TRW PT5651 RF transistors as the Driver and P/P finals. It is a 10 watt 2-18 mhz transceiver used in the early to mid 60's. The finals are shot and I am looking for replacements. I can not find data sheets, specs, are any information on these anywhere. Its like they didn't exist. I am looking for any type of replacement. I can't even tell if they are Pnp or NPN. They are single stud mount, with 4 solder tabs. The curcuit is broadband, and the B+ is 12-14 volts. Thanks for any help. Joe Munson WA4VAG Does the transceiver have a model number? |
