Post subject:  Need help choosing right equivalent for Ge transistor

Hello! I have a portable radio tape with both Si and Ge transistors - Craftsman or 'Record O Matic' https://www.radiomuseum.org/r/craftsman_record_0_matic.html . It had some problems on tape, poor sensitivity on AM, overlap on some FM near stations ecc. Hardly I have solved a part of them including new socket for power cable, new socket for batteries, new capacitors. By mistake I broke a pin from the final transistor 2SB364. I can't find this, but can I replace it with either a pair of 2SB324 or a SFT323?
Here is the diagram (taken from the radio).

I looked at 2SB364,

I Googled : https://www.google.com/search?q=2SB364&rlz=1C1CHBF_enUS713US713&oq=2SB364&aqs=chrome..69i57.1159j0j7&sourceid=chrome&ie=UTF-8 It shows there is a NTE equivalent NTE102A

AC128 but change both outputs.

Does anyone have an account on RadioMuseum for helping me taking this diagram: https://www.radiomuseum.org/r/orion_amfm_cassette_tape_recor.html ? This is another radio tape very similar to the model I have and the diagram would have a better quality scaned that the once I have. Thanks a lot!
