identify a transistor.

[Edwin the inductor]

Hello! I working on reper a old analog radio. the problem is that one of the two identical channels dont work. the problem is that the card that gives the amp som strange pawer, haw a no named broken transistor. it's a two channels radio so I have still a identical working transistor, now to the real problem how cud I now wot transistor it is a transistor tester dont work i cant fine anything in the PCB diagram?
Help!
here is the link to the service manual and som schematics

How old is the radio?

Did you unsolder the transistor from the circuit before testing it?

Could it be germanium, which is why the transistor tester didn't work?

Take a picture of it and post it here that shows any letters/numbers etc.

RCA 38202?

Edit:

Is the other identical one easier to read the numbering, perhaps take a photo of that as well.

Couple of hints, find a date code somewhere let us know and look up RCA transistor manuals from around that time, before and after the date. It may be a custom spec part so searching could be hard.

Always provide as much info upfront about what you are actually working on. Even back then the same radio could be sold as several different brands or models. So it could be a case of having several schematics or they copied someone elses design. Link schematics if you have them.

Could be RCA 39202. I could not find either of them so far. OP may have to do an exhaustive search on line.

Could it be RCA 39302?

The equivalent of RCA 39302 is NTE 152 - NPN Si AF Amplifier.
