I'm looking for a back metal cover for my JCM900 Head. Possibly a user manual. It has a number stamped on the rear of the amp that is Z02174, might anybody know what that number stands for? Any suggestions? Thank's.
Hello John,
The serial number on the back of the amplifier (Z02174) means it was manufactured in 1991. If you would like to e-mail jgreen@marshallamps.com i can send you a manual and let you know how to order a new back.
