An All New Original Circuit Dynaco PAS Tube Preamplifier!
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.
I went with the original dual 2000uF electrolytic capacitor design for the filament supply except I used diodes instead of a selenium rectifier.
Retains the 12X4 rectifier tube, just like the original design.
By retaining the original circuit, power supply and filtering, this PAS has the warmth and sparkle that is missing in so many modern upgrades & designs.
The selector switch is a modern 6 position, the volume and balance controls, the bass and 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 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 satin black.
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: Multicap RTX (phono stage), Cornell Dubilier 940 Series, Nichicon Icell PWS Series (made in Italy), Panasonic and Illinois Capacitor.
The 20/20/20/20 quad filter capacitor is brand new, made by CE mfg.
The included tubes are: a matched quad of new Mullard 12AX7 long plate tubes
The 12X4 is also included, it is a NOS RCA "black plate" vintage tube.
Sale is for the preamplifier only, the amplifier and speakers shown are not included.
This unit has been tested for over 40 hours and exhibits no hum.
