Marshall 2203 JMP Master Model 100W 1980


Product Code: AP2920

$ 2,025.00

The JMP Master Model 2203 is what would become the mighty JCM800 a year later, in 1981. The circuit is identical to the original JCM800. This amp has the original Drake power transformer and choke, but with a MagicParts TF-170 output transformer, which is the same used in Dumble ODS amps. There were mods done on the amp previously, but have since been returned to stock. A couple of resistors have been changed, but the majority of the components are original. This example is missing the Marshall logo on the front, but is otherwise in clean cosmetic condition.
