Other Notes: "The special capabilities of vacuum tubes are fully recognized in this new Dynaco high power monophonic amplifier for the professional sound installer. Vacuum tubes are decisively favored in their ability to withstand all manner of user and signal abuse — conditions frequently encountered in discotheques, public address and musical instrument applications. Continuous duty operation at full power, while maintaining safe operating margins; protective isolation of teh load from the driving circuits; and uniform power output into a variety of load impedances are hallmarks of tube designs.

The Mark VI delivers all these attributed with the distinction of unsurpassed sound quality at high power in a manageable package at sensible cost.

The essential circuit concept is an extrapolation of the famous Dynaco Mark III design which first popularized high quality, high power music reproduction. Notably simple, this circuit reflects a sophisticated directness which contributes to its remarkable listening ease. The sonic quality of tube amplifiers is largely determined by the output transformer, and it is here that Dynaco's patented designs have been supreme for two decades. The Mark VI uses a new output transformer developed especially for this circuit, so conservatively rated that it can handle twice rated power over most of the audible range, opening the door to the "tube sound" so avidly sought by perfectionists.

The design is strictly to professional needs: no-nonsense, rugged, rack-mountable, versatile. Recessed controls for the input level, bias adjustment, and 4-position range switch for the lighted meter; speaker fuse holder and power switch are on the front panel. The inputs on the rear apron are for both phono jack and XLR connectors, plus an additional phono jack input through a high pass filter. The output is via a barrier strip for all impedances, plus a phone jack for quick connections." - Dynaco
