Quick fried amp question

[revoracing247]

i heard that you should replace all the transistors, not just the ones that are blown. parts from different lot numbers could have slight variances in them, which can possibly make the new parts work harder (or the older parts work harder).

so you're saying i should buy all the transistor and from the same place so that they all are made from the same people and so there's not as much deviance between them?

also if i do have to replace all of them, is there like wiring diagrams for these? cause it seems really hard to keep track of where all the diff transistors go.
