SOLD

we'll have another one ready soon

Assembled, tested and ready to ship now. Also called the PAS-M, this Dynakit PAS Tube preamplifier operates silently and sounds amazing with the warmth, sparkle and imaging detail that is missing in so many modern designs. Don't take a chance and throw your money into a used preamp that has 50+ year old parts, unless of course you prefer spending as much time working on it, worrying about it, and fiddling with it, as much as you do listening to it.

Photos shown in this listing are of the actual preamplifier being offered.

The Features:

• Traditional Dynakit power/filament supply + filter cap + 12X4 tube

• Original Dynaco Circuit - for the classic sound signature that we love

• New Genuine Dynakit circuit boards, latest revision with integrated ground planes

• Carbon film and metal film resistors

• Audio grade film capacitors

• Modern 6 position rotary selector

• Updated input-output panel with corrosion resistant Gold plated RCA jacks.

• 5 high level inputs for CD, Tuner, Tape Deck, etc.

• 1 dedicated low level MM phono input (47K moving magnet)

• Phono ground binding post

• Volume, balance, bass and treble controls, all new of course

• New 120V Dynakit PA-211 transformer, fused AC mains

• 22 gauge stranded wiring, soldered with Kester 63/37 eutectic solder.

• Brand new chassis and Brown vented cover from Dynakit

• Aluminum faceplate with solid aluminum knobs.

• Blue LED pilot lamp with adjustable brightness

• Micalex tube sockets from Belton

• Set up for high impedance amplifiers @ 470KΩ - like the ST-70 & ST-35

• The best tube preamp for driving the Dynaco ST-70, ST-35, MKIV and MKIII or similar high impedance tube amplifiers

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

• The pilot lamp is LED with adjustable brightness

• The volume control, balance control, tone controls are quality parts from Bournes & Alpha

• This PAS model uses the new Dynakit filament supply with a multi-section filter capacitor and 12X4 rectifier tube.

• This is not a rebuild, it's all new, a modernized version of the original PAS.

• Fully tested and burned in, a beautiful sounding preamp. 

Most people have never had the chance to listen to a properly functioning PAS, especially one like this. Many opinions have been formed based on listening to a "garage sale" grade unit which was just removed from long term (and usually improper) storage or have tried using a unit that is simply worn out from decades of previous service, not exactly a means for a valuable assessment. Long periods of dormant storage are the #1 enemy of electronics. Also, many of those preamps were assembled with poor soldering and improper wiring. This one is built right and I'm confident in saying it's on par with other tube preamps costing considerably more. 

This PAS Tube Preamplifier includes four new JJ-12AX7 "short plate" tubes and one NOS Tung-Sol 12X4 rectifier tube.

This is an all new, brand new build using all new parts and components, it sounds amazing.

The aluminum faceplate has updated (modern) nomenclature printed on around the selector knob, it matches the selectors functions and also the rear panel orientation and label. Again, the indicated selector functions match the rear panel labeling and follow the designated order on both the faceplate and the rear panel label. There are no provisions for a filter, loudness or tape monitor switch, those functions are eliminated. The stereo to mono blend switch is also omitted, and the volume control is relocated above the balance knob as shown in the photo.

The rear panel has jacks for 5 line level (high level) inputs and one phono input and there's a phono ground post.

I have paired this PAS with a Dynaco ST-35 an ST-70 for testing and burn-in, the results were wonderful, as expected. This is what a Dynaco PAS is supposed to sound like. Very pleasing, warm, lush and detailed with the glitter and nuances we love so much.

 NOTE: Due to limitations of the selector switch, there are no tape loop or tape monitor functions. You will not be able to use this preamp for recording. This preamp is designed for playback only. It is suggested to have only one source at a time playing to reduce the potential for crosstalk.
