This preamplifier operates silently and sounds absolutely amazing with warmth, sparkle and a holographic detailed presentation that is missing in so designs. A perfect companion to drive your tube amplifier.

The selector switch is a modern 6 position type.

The rear panel has jacks for 5 line level inputs and one phono input for a MM (moving magnet) type t phono ground post. The nomenclature printed on the front panel at the selector still reflects the designation of the original selector and therefore does (verbally) with the new selectors order of operation and input arrangement on the back panel. (See the photo in the listing for a visual representation to clarify further).

Operation however is logical, simple and straightforward. Phono is now located at the far left location labeled (special) the remaining positions follow a clockwise rotation and match the order of the jacks in the rear panel. Starting at phono (special) and rotating to the right you have (Aux/CD) w located then (Aux/MP3) where phono is labeled, then (Aux/Tuner) where it says FM-AM, then (Aux1) at the position marked FM-MPX and finally (Aux labeled spare. See notated photo in the listing for clarification please. 

NOTE: Due to limitations of available selector switches that will fit this chassis, there is no tape loop or tape monitor function. You will not be able to use this preamp for recording. This preamp is designed for playback only.


The genuine Dynakit PA-211 power transformer is brand new and wound to operate from a standard 120V-125V outlet. (no voltage reducer necessary

There's a brand new power cord and the pilot lamp is an adjustable LED sitting behind the amber "power indicator" pilot jewel.

This model has all of the switches for loudness, filter and tape monitor deleted. The stereo to mono blend control is also omitted. 

This is not a rebuild, it is a brand new, updated and modernized version of the original PAS.

Basic instructions and initial setup guide with diagrams are included. Email and phone support provided as needed.
