About the MK IV
The Dynaco Mark IV is a vintage monoblock tube power amplifier, available originally as a kit or factory-assembled unit. It uses a push-pull pair of EL34/6CA7 output tubes, a 7199 input/driver tube, and a GZ34/5AR4 rectifier, producing 40 watts of continuous output with 4-, 8-, and 16-ohm speaker connections. A stereo system requires two Mark IV amplifiers; “pair” refers to two individual monoblocks rather than a separate model.
