About this model

The Model 5 was Marantz's 1958 mono power amplifier, a less powerful companion to the Model 2. Reference listings give 30 watts in ultra-linear mode, or about 18 watts in triode after changing internal connections, from two EL34/6CA7 output tubes, with a 6BH6, a 6CG7 and a GZ34 rectifier. A pair makes a stereo system.

This pair had come out of long storage with a few capacitors replaced and no hum or noise.
