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.

Does the transceiver have a model number?
No marking of any kind on the unit. But I believe to be a Hallicrafters TR-9.
