Default Marantz output transistors

I recently picked up a Marantz 2265b receiver. One pair of the outputs appear original (they are marked Marantz) and are 2SB645 and 2SD665. THe other pair are Toshiba 2SD424 and 2SB557. From what I can see, the Marantz are a correct matched pair, and the Toshibas don't cross to them, nor do they seem like a match to each other. I am just assessing the amp right now, and all outputs look good. Haven't even powered it up yet. Are these ok outputs, or should I look to be subbing in MJ21195/96, as I have read are good as subs for the Marantz transistors?
