TRW Transistors
No, mine was a different model. This is really cool looking.

I can not find data sheets, specs, or 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? No marking of any kind on the unit. But I believe to be a Hallicrafters TR-9. That's a bad-ass looking radio. http://www.qsl.net/la5ki/big/tr9.jpg |
