2250b output transistors

[Robbor]

Hi everyone, I'm in the process of rebuilding my 2250b and have a question on the amp boards 2 output transistors 2SA753 & 2SC1343. Do I have to match both of the above transistors on both of the amp boards or is it ok to replace just one sketchy transistor that someone installed years ago?
Fyi....The other amp board has the correct output transistors installed.
Thoughts?

I've always been of the mind that if you change one output, you change them all (with some exceptions of course). MJ21193G/MJ21194G outputs worked well for me on my 250M and are the appropriate replacements for the 2250B. Bought mine on eBay for $20 a pop from peace.love.and.music. They matched them up for me also...

Ok. That's what I was thinking too.Thanks. I used Ben's components when I recapped my 2270 a couple of years ago. I'll get in touch with him for a quote.
