I did, I looked through a few threads and it was kind of a mixed bag, some were saying they could be subbed for each other and some were saying they couldn't be subbed for each other, and I was wanting to see if anyone could confirm either way.

In fact, some old transistors go noisy, like the dreaded 2SC458, for example. Is good to check.

The only trouble you may have is if the transistors are direct coupled in the
power amp. I would do one channel at a time & be sure every thing runs cool.
To look them up replace the K with a 2 & you got the Japan ##
The transistors are Korean, Scott labeled korean stuff in the "Quad" era. . IIRC
the last few real Scotties were quads & still built in Maynard Mass. The factory was 5 miles from my old house.

Gotta be careful with those Korean KSC transistors. They may be electrically equivalent to the Japanese 2SCs, but I remember the pinouts being different. You'll have to do some wire bending before installing those KSCs. Check data sheets first (NTE/ECG books are OK, you're just checking pinouts).
