Default Replacements for RCA 16505 and 16506 transistors?

Hi all,

I'm trying to repair an Armstrong 626 tuner amplifier for a friend of mine:
https://www.vintage-radio.net/forum/...57#post1534257

Unfortunately, two transistors in the right channel audio driver circuit have failed: RCA parts 16505 and 16506 (see picture below).

Does anyone know whether a modern replacement part is available, please? Or does anyone know the specifications for these transistors (presumably an NPN/PNP pair)?

Many thanks,

Adam
