Arrow Sansui SM-3000 (PPI 2150M) output transistors replacement

hello guys
I stole this baby of ebay for 40 bucks sold as blown .Im guessing no one bothered to check that this is PPI 2150am in Sansui skin and this amp is mint with box ,harness ,manuals for 40 bucks ill buy it any day .Board is in mint shape and the only issue found was 1 shorted output 2n6487 and the other 4 in this channel test fine .The amplifier power on and plays fine with 1 transistor missing.My question is there are 5 pairs 2n6487/2n6490 i do have 2n6488/2n6491 can i replace them and how
-all transistors in the channel or just the group of 5 with 2n6488

The 6488 and 6491 are good subs.

I'd replace all 10 of the output transistors in that channel.
