Matching tubes


I have a pair of Canary M350 Mono blocks. and a Cary Slp98P preamp. The tubes in the preamp are matched. I had one tube (A  300B) go bad in the power amp. Is it as important to have matching tubes in the Amps? Each 300B is biased manually. Thanks in advance.

I don't used matched power tubes.  My two power amps use 8 KT-88's each. When a tube goes, It's replaced.  I've been doing it that way for years.
