Transistor replacement InterM R500 Plus (With datasheets)

[HarleyM]

Hi, I got an InterM R500 plus amplifier, with burnt resistors and final transistors. The broken resistors are R121L, R122L, R128L. Im gonna change them with all the transistors and base resistors.

There may be some damaged transistors. Q108L, Q109L and Q112L, Q113L. I can't find direct replacement and i don't know what to look after.
I been searching around and came up with these replacements, are they OK to use or is there a better equivalent?
These are
Q108L PNP 2SA 1546 NEC A1546 Replacement ----->BD14010STU onsemi
Q109L NPN 2SC4001 NEC C4001 Replacement -----> BD13910S onsemi
Q112L KTC4370A-Y-U 2SC 4370A Replacement -----> TTC011B,Q Toshiba
Q113L KTA1659A-Y-U 2SA 1659A Replacement -----> TTA006B,Q Toshiba

All datasheets provided with amplifier service manual.

Thanks
HarleyM

and for 2sc4001 the ksc2682 (or bf469 or bf472)
