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.

Holy smokes! Those should be able to crack the foundation!

Are you willing to describe the rest of your system to us who have naught to listen to but an AM transistor radio? What speakers? Preamp?

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..
