Genuine 1977 Marshall JMP Master Model Mk2 Lead 50W head. Serial number S/A 090261J — the S/A prefix confirms the 50W spec, and the J date code places production in 1977, which matches the internal inspection label also dated 1977.


Still running its original capacitors — no recap has been done. It works correctly as-is, but a service and cap replacement would be sensible for anyone planning to gig it regularly rather than something that needs doing to make it functional.

Tested and working fine — amp powers up, functions correctly, and sounds as expected on both inputs.

Control knobs are aftermarket replacements, not original to the amp.

Please review all photos carefully, including the internal shots — they form part of the description and condition report.
