Default Nakamichi MB-100 transistor burned - Need info

I have an MB-100 in that I need some info on. I have seen a few posts on here with others that have worked on them. I have a bad transistor. Possibly 2. (only a faint sound coming out of the output RCA's) ... Here is what I am looking for Q401 and Q402 ... I have 24-52 on one trans and the other one has a **-51 . Can't read what is on there since it has a burn mark. Anyone have a board for one they can look at, or possibly a schematic? Perry? Anyone? Maybe I am stretching here, but anyone possibly have these transistors in stock? See pic below. Thanks in advance.

Anyone? Does anyone on here still have one that they could check their board? It is the main board in the disc section. Thanks...

From nak mb75 service manual.

desig, part no, description
Q401, 0k10030a, tr, 2sa1036k-r
Q402, 0b14011a, tr, dtc114ek

And i'd suggest fixing those leaking caps too.
Although by the looks of the plate through holes it may be too late......

Thanks for the help. I appreciate it. Now on the hunt to find the transistors. Forums sure make it a lot easier than the old way of guessing, or waiting forever of getting a schematic from the mfr...
