I've found component values all over the place on various Mesa Schematics.
Mike Bendinelli has been with Mesa forever and is always my "go to guy" for the Mark Series Amps.
Why the hell don't you just contact Mesa direct and ask? That would be the simplest thing to do!!!
Unless Mike has retired already, you might be able to email/call direct.
Even recently, I've found Boogie Tech Support some of the best in the business from getting answers to obscure questions, to getting OEM replacement parts for amps that have been long out of production.
You are wasting tour time asking that kind of stuff here.
You will only get crickets.
Spend some time internet searching, and calling on the phone.
Put some effort into figuring out things on your own.
It is time better spent, and you will learn something!!
