a greeting to the group.
in the arduous task, at least for my abilities, of "restarting" my old Yamaha Ca-610, I ask for help in finding transistors equivalent to the originals.
the originals are:
thanks in advance for any suggestions.

the originals are:
- 2sa844
- 2sa777
- 2sc1509
- 2sc1918
- 2sc458
thanks in advance for any suggestions.
Thanks RJM1.
but more "common" equivalent components do not exist?
I live in Hungary, difficult supplies, difficult shipments, taxes and additional costs.
something that can be found in the local shop (60 km from where I live, in the center of Budapest).
I'm probably asking too much.

You just look up the specs in their data sheets on line and pick a similar transistor from the selector guides at a vendor like Digikey or a manufacturer like On-semi. In some cases you do not need, for example a 60V part if your amp runs on 40V. In many cases, a good match has a different pin-out, which means you have to carefully twist it to fit the correct PCB holes. The 80V,1A parts are probably better replaced with TO-126 types like MJE340, MJE350. None of those transistors are anything special and the last two could be 2N3904, 2N3906.
But fixing amplifiers, the odds are you will blow it up unless you understand and test every detail. There are so many ways to mess up and transistors blow in an instant. If you replace one part at a time, you will just destroy the new parts you have replaced. In some cases, the maker has committed an obvious oversight that needs to be modified to prevent repeated failures.

Thank you!
you are nice but you look like salespeople.
I'll give you an example: the site english.electronica-pt.com gives the Bc213 as an equivalent replacement for the 2sa844.
even if the Bc213 is not found in Hungary, it can be replaced by the Bc557.
so and I probably phrased the question wrong.
