An All New Original Circuit Dynaco PAS Tube Preamplifier!

Contact us to discuss details, payment / ordering options and pricing.

This PAS is built in a brand new Dynakit chassis with a new custom made aluminum updated faceplate and new knobs.

Built with ALL NEW PARTS! - This preamp sounds absolutely amazing!

USA made replacement circuit boards that are identical to the original PAS boards except in color.

The included tubes are: a matched pair of NOS Mullard 12AX7 (Hammond labels) long plate tubes for the line stage and a matched pair of NOS GE 5751 tubes for the phono board. The 12X4 is also included, it is a NOS GE 12X4, a perfect vintage tube.

I went with a modern design for the DC supply and the filter capacitor. This is a more reliable and really nice upgrade for a PAS.

The B+ / DC is derived from a 12X4 tube, just like the original design.

By retaining the original circuit and a 12X4 tube rectifier, this PAS has the warmth and sparkle that is missing in so many modern upgraded PAS designs.

The selector switch is a modern 6 position, the Alps volume and Bourne's balance controls, the Alpha bass and Alpha treble controls are all brand new parts.

Every piece of this preamp is new - this is not a rebuild, it is a brand new modernized version of the original PAS and it works great and sounds awesome.

The genuine Dynakit PA211 power transformer is brand new and wound to operate from a standard 120V wall outlet. (no voltage reducer necessary)

There's a brand new removable power cord and the pilot lamp is an adjustable LED sitting behind a genuine NOS Dynaco amber pilot jewel.

The rear panel has jacks for 5 line level inputs and one phono input for a MM (moving magnet) type turntable. There's a nice phono ground post back there too.

All the knobs are new as is the cover, the cover is the standard Dynaco Brown.

The stereo blend switch, filter switch, tape monitor and the loudness switch were eliminated, this helps keep the signal clean by reducing the wiring, solder connections, and other entry points for electrical interference.

This preamp is very simple to operate. It sounds super smooth, sparkly and musical, just like it should.

Only high quality metal film and carbon film resistors were used.

The high quality film capacitors are: IC, Panasonic and CDE 930 Series (phono stage), The line stage uses JB JFX series, IC and Mallory films.

This unit has been tested for over 12 hours, sounds fantastic and exhibits no hum.

The original Dynaco circuit with its all new high grade components is hard to beat.
