Hi guys, i'd like to ask you an advice. An accidental short caused some damages on the Main Amp PCB and i have to replace (testing bad) transistor Q411 in the scheme below which is a 2SA1017. I haven't the same transistor but i have KSA992 and it seems to me a good sub (maybe fT too low?). What do you think about? Eventually i have his complementary KSC1845 for replancing Q413 (2SC2363)
I'm attaching the scheme and thank in advice! :)
P.s. I also have in stock KSA1220/KSC2690 which are in TO-126 format
