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.

Wow, that is quite an amp. Most tube retailers provide matched sets of tubes for no additional cost or a small fee. So why not get matched sets? Not sure what that amp really needs the manual says have your dealer replace the tubes, no help there but the power tubes are run by sophisticated electronics so it's probably one of those that doesn't require matched tubes but that is just a guess.  

This is totally obvious, but at $35K MSRP for the monoblocks be totally sure to get expert advice before retubing these beasts.  It's interesting, I did not realize that there were any combination solid state/tube amplifiers built.

Why are you looking for tubes on your new 35K monoblocks?  They certainly are not worn out yet, in fact they should last at least 10 years as the power tubes are not run hard at all. Same for the signal tubes.
