I just received a nytech cta 252 to repair.
it is one of the very first model.
he suffered quite a bit of damage but nothing irreversible.
it is one of this generation with really old transistors (bcx32 / 36, bc309c, bc238c)
I wish to restore it so as not to distort its original identity and above all not to unbalance it.
so I ask those who really know this circuit to tell me what equivalences I can use (except for power transistors) and what are the critical points to respect in this circuit, because there are a lot of diagrams on the internet but nothing clear and I don't want to upgrade it obelisk or ion way.
idem, if transistors are "critical" in termes of gain or spec, I would like to know.
thank you
