The M13A is a rare amp. It was only made for a short time in 1965 after it replaced M13. The most noticable change for the M13A was the switch to the silver trim motif (a change also carried out for the M7, M12, M10A, and M15A at about the same time). While early M13's came with 4 tweeter speakers to compliment the 15" Jensen, the M13A only had the single 15" Jensen.

The M13A would have appeared sometime in the spring of 1965 and was dropped later that year. The addition of the similar M20 in the fall of 1965 made the M13 somewhat redundant.

While the M13 was known as the "M13 Imperial", Magnatone also offered an "M13 Dual Imperial" which was an Imperial paired with the RS-2 15" matching extension cabinet.


Estey engineers James Evans and Maurice Varin designed a single chassis that made of the Custom Series amps could use. Notice the extra unused noval holes in the chassis.


Special thanks to Red Rock Amps for the pictures of this M13A.
