I work in the warehouse at guitar center and had been looking for a nice vintage tube amp but didn’t really know what I was looking for. I saw the MM sitting in the used amp section and it caught my eye immediately. I fell in love with it as quickly as it intrigued me and I just took it home today. Have done minor research over the past couple weeks and know it was manufactured between 74-79 and was stoked to see that I got it for a pretty fantastic price.The serial is BN04941 I was wondering if anyone could share some knowledge with me!

Help dating my 115/65
Hi,
If you take the amp chassis out, there may be a date written with a marker pen on the circuit board. You can also date the transformer using the Schumacher manufacturer date codes. You can google how to interpret the codes on transformers, potentiometers and speakers, if they are still original.
On this website you can do a search on "serial numbers demystified" as a topic...but it seems the serial numbers do not mean much for dating the amp..but they can tell you a bit more about the amp itself.
115/65
I don't really care so much about exact dates. So I can't help you there.
But I am slightly interested in the timeline.
115-65rt is the first model I know about. (reverb, tremelo) It has the small tube as well.
115-65rp is next I think (reverb, phaser) solid state phase inverter from then on
115-hd (distortion) models came next in several amperage ratings, and in both black and white tolex.
Not much I know but that's all I got haahahaahah
Since junk accumulates on top of amps, and there is nothing you can do t stop it, I make amp shelves for myself.
These have lugs underneath to clear the handles and level out. They overhang just a little all 'round, in case of spilled fluids.
