Hello. As it says in the parts list, those transistors should be BC550BTAR, but what I really have are BC550C. Which one is a correct type (or even any alternatives) to order spare ones to mix and match my BC550C's?

Perfectly OK to use BC550B or BC550C. Just make sure they are all the same. The C has higher gain, but the B lower noise. So pick our poison. :)

Thanks for the quick reply Russ.
This is for my second Legato. I "eliminated" one of those transistors while assembling the first board :)
So, for the symmetry reason I guess I better off going all the same on both boards, i.e. BC550C.
Thanks,
Alex.
