MC901 monoblock tube matching Q

I'm new to tubes... I have 2x MC901 monoblock amps. Each amp requires 8x KT88, 4x 12AT7, and 2x 12AX7A tubes. Do I need to match all these tubes? And do I need to match tubes for both amps together (i.e. 16x KT88 matched, 8x 12AT7 matched, and 4x 12AX7A matched)?

Thanks for your help.

Preferably yes, it’s always good to install a matching tubes.

The power tubes are in quads and the signal tubes are in pairs. You can just throw one in, it will work. How it will sound is a different story. I'd guess just fine.. How picky are you. 10 years from now, start looking..

My advice to you is to leave it alone.  You didn't spend a bazillion dollars on those jewels to f around with them.  Many years from now when you do need to service them, ask a pro - not a board full of "experts."
