I generally do NOT farm out transistor replacements, anybody who is REALLY qualified, won't be asking questions, just figuring out just how far they have to go in reverse engineering the thing, to spot the mistakes and marginal conditions (and they ARE there, or we wouldn't benefit from replacing the originals) and get something more suited in there. Since I usually leave plenty of margin in my recommendations, identifying locally available equivalents (starting with voltage, amperage, wattage, gain and bandwidth) hasn't yet bit you.
I really don't have much of an index of the last 16 thousand or so posts, that I can call up somebody else's recollection cold.
I posted rules of thumb for capacitors, I would have stressed caution on anything involving transistors.
You could look for any of my responses in any sa-9500 threads. And then sort through a lot of posts looking for what YOU have seen, and I have little inkling.
Another thing to remember, is that some of my favorite transistors have been discontinued, and as such had to change the recommendations based on gained experience with other transistors. One loss that rankles and has been a pain is the loss of the to-92L version of the ksc2310, and then finally the complete loss of ANY case type of ksc2310. Forcing the less liked choices between ksc2690 and ksc3503 transistors because of their much larger TO-126 case (because of physical FIT considerations primarily, in other regards they are just fine).
