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.
