My brothers MM 212-HD

bmw05645

Hello, all, I'm a new member, and this is my first post. 

Been playing guitar and bass for quite a while; my brother did as well

He passed away recently and left me a lot of gear; including a 70's vintage

Music Man 212-HD. Serial number is C003872, chassis number 2475-130, 130 watts

There isn't any info on the tube chart, and I can't see the transformer date without taking the cabinet apart.

Might any of you have any advice for determining what year it is? I'm excited to have it; my friend had one in 1974

when I was just learning to play; gotta have it looked over as it hasn't been played in quite a while.

Glad to be a member, thanks for any advice y'all might have

Unfortunately, SN's on MM usually don't do much. Does it have the 12ax7 driver tube or is it SS driven.  That's where we usually start. That dates it to before 78 or so or after.  Pics help also. Back and front.
