The M-60 MkIII is a 60 watt class A triode fully-differential and balanced OTL with a single stage of gain. It has been in production in various forms for about 18 years, starting initially as the M-50.

The topography of the circuit is unique; it is also simple, reliable and gets good reviews. It is designed for maximum performance without maximum cost, using a vintage styling to execute proper cosmetics. The amplifier is hand-wired with many custom-built parts and materials, and sets build quality standards for the industry. M-60s are quite rugged and many older units are still very much in service. Older M-60s can be updated to the latest level with warranty reactivation.
