I have a vintage AM pocket transistor from '60s. It have some sentimental value more than I prefer to repair it, however I would try...
The first problem I notice is one broken old style trim cap ("the white one" as shown on picture). However, I failing even to find datasheet for these old trim caps. I doubt they are still in production, however, without schematic it is hard to replace it with nowadays. I have no better idea except to try to buy any other similar vintage pocket transistor and salvage it.
Anyone is aware these are in production in small quantities at least?
Even datasheet pointer can be helpful.

It's not a cap, rather an IF (intermediate frequency) transformer. Most likely a tuned style. Essentially a threaded ferrite core over 2 coils and a capacitor.
There should be some markings on it that can help determine the values.
Google: miniature IF transformers
Also, check out some vintage/antique radio sites. There's still a ton of these out there

Thank you very much for clearing all!
