Dynaco PAS-3 series II


While a totally new design,the series II has in common with it's illustrious predecessor (the original PAS-3X) the same striking simplicity of operation, conservative design, full-featured operation, Spartan beauty, and Dyna tradition of value.

The PAS-3 series II includes as standard a true state of the art phono preamp section and full provision for tape dubbing for the home recordist.

This kind of flexibility and full featured styling is without parallel in affordable vacuum tube preamps.
