Hi to the Archivists
I got me a RD112 100w with the following info Chassis No 2100RD
Id 2100
Serial no 08949DP
Weight 27k
Logo Black background
White Sticker on
back at right says 83-1
Trans (Left) 200-130 250
EIA606-103
" (Right) 4-130
EIA 606-121
I'd appreciate it if someone could tell me when this was built and if the speaker would be a EV model cuz it does'nt have a sticker of any sort .The magnet on the speaker is round and has a hole in the center with a wire mesh .Thanks

I also own a MM RD112 100....I PURCHASED MINE NEW IN 1980 AND I BELIEVE THIS IS THE FRIST YEAR THEY WERE OFFERED..
YOUR SPEAKER IS A EVL12 ..MINE HAS THE SAME..MM DID NOT PUT A LABLE ON THE EV SPEAKER ON THIS MODEL...THE SPEAKER MAGNET IN THIS AMP IS VERY HEAVY AND THE FRAME IS A ALUMIUM CAST..
I HAVE PLAYED MINE ALMOST EVERY WEEKEND SINCE I OWN IT AND HAS NEVER FAILED ME..
HOPES THIS HELPS

Hi Terry
....Yeah I got this badass about a month ago and can't wait to gig it.Seeing as you've had yours so long maybe you can give me a few pointers as to replacement tubes,that is, if yours runs on 6L6's.Thanks Man!

Hey Spino...
I use Groove 6L6's and have had since i replaced the orginals....these babies work great for my kind of playing,which is rock, blues, and country.
These tubes will lasted about 2 years and were biased before i played thur them..the tube were also a matched pair...
I will say the orginal GE slyvania tubes were great and lasted a long time before i replaced them..
There are sereval differant brands on the market these days, but the groove tube seems to do the trick for me.....
I hope i helped you a little....
TERRY
