If the small signal ones, take any Ge transistor with unity gain good enough and Vce max 30 or so V.
For the output....you could try whatever it is electrically good enough to verify radio's functionality and then dedicate your efforts to finding the proper replacement. They pop up on eBay.
Also, you could possibly look into some Russian or Eastern European old transistors, they do exist on eBay. Gosh knows, they might be physically compatible with your heatsink.

Like this one, is a 20V Hi-F (90MHz) PNP, small signal.

From memory (I do not know if they would fit physically) the Ge output transistors are:
P201
P214
P215

Large power

P210

Not a very good transistor as the unity gain Frequency is low.



P214, a good transistor.

So is P215.



P201 not as good but likely would do.
