Here's a pair of amps you will be proud to own and use for a lifetime, as the photos reveal, these are very nice. Beyond the build quality I went further to assemble a complement of quality and highly reliable components to ensure the performance and sonic abilities of these amps. To say they sound very musical would be minimizing. Keep in mind, an amplifiers job is simply to amplify, that's what these do and they do so in spectacular fashion. Your preamp and speakers will ultimately complete and determine the end result of your systems sound. These amps are very transparent and have the power to push even large speakers to incredible listening levels, if that's your thing.
These amps feature Upgraded Premium Dynakit 80/40/30/20uF multi section capacitors which are rated for 550V (600V surge)
Each amplifier has a genuine Dynakit P-782 power transformer plus a an A-431 Output Transformer - The original (vintage) transformers are inarguably excellent, but they were designed to operate on 117 volts (think 1950's). Today's household AC current is often near and occasionally higher then 125 volts, so the use of a "step down" or "bucking" transformer is necessary to reduce the voltage down to a safe operating level for any vintage amp having its original transformers. These modern Dynakit transformers are manufactured to work from standard, modern 120-125 volt household AC current. They operate cooler, produce less distortion and outperform vintage transformers in every category. These transformers were reverse engineered from the original designs using many modern manufacturing technologies and superior insulations. These are super high quality USA made transformers that meet and exceed every aspect of the originals. There's more......if there were some sort of "magic" in cloth covered leads, Dynakit would have certainly insisted on using them. The truth is, there's simply no magic in cloth covered lead wire. There's nothing wrong with cloth leads, they were the the standard of the time, but in any comparison, these new transformers are better than those old originals. Modern advancements in materials, combined with traditional methods and better technologies used in the manufacturing has resulted in absolutely superb transformers that produce improved sonics and cleaner power. These transformers provide less distortion and increased reliability. This is not a 50 year old amp and is not pretending to be one. This is a modern amp based on a ingenious and very successful 50+ year old proven design. An inrush current limiter is incorporated into the AC mains to gently apply power during initial start up.
Each MK III circuit board is a stock Dynaco PC-1 using the original circuit and a single 6AN8A tube. These boards feature CDE 942C series capacitors for superior sonic performance and reliability. The 942 series have polypropylene film and dual metallized electrodes for both self healing properties and high peak current carrying capability. These are simply some of the best caps on the market at any price, they sound phenomenal. The smaller caps are Cornell Dubilier dipped silver mica. These amps sound stunning! The resistors are a mixture of 1% screened metal films and 5% carbon films for superb accuracy while retaining the warmth so desirable in tube amplification. Brands are TE, Vishay, and Dale. The tube sockets on the PCB are the high quality Belton Micalex type.
The bias and power supply features F&T 100uF 100 Volt rated electrolytic capacitors for outstanding electrical performance.
All of the wiring is 20 AWG USA made wire and is carefully and tastefully routed and secured in the chassis. All soldering was done with Kester 60/40 rosin core.
Of course the amps have the Genuine Dynakit Shielded choke #C-354 for extra quiet operation.
Original style screw terminal speaker jacks for 4, 8 and 16 ohm loads.
Identically matched JJ KT88 Tubes, tested and analyzed using the ROE computer tube matching system - one of the best rated KT88 tubes on the market. Ordered brand new as a matched quad just for these amps. The tubes are unlabeled & unmarked. These were purchased from a dealer who had a case of select JJ KT88 tubes that was originally sold & shipped to a West Coast manufacturer intended for private labeling to be used as the OEM tubes in their high end production amplifiers. These tubes were hand selected, tested and graded, these were a great find and they sound as beautiful as they look!
Test matched and sweet sounding pair of vintage (Gt. Britain) Mullard 6AN8A tubes with GE labels in their original boxes.
New Tung-Sol 5AR4 / GZ34 rectifier tubes with their original boxes
3 Prong Grounded Power Cord
Genuine Dynakit mirror Polished stainless steel chassis with Brown covers and Dynakit labels.
These amps were designed and built to be a true identically matched set.
These are modern, brand new amps made to operate from standard (USA) 120-125 AC current. You do not need a voltage reducer to run these amps, just plug them in and go.
These amps sound fascinating, a crisp, rich and most articulate soundstage. Driving a large pair of horn loaded cabinets with 12" woofers these amps bring the room to life effortlessly. The vocals, horns and strings are almost disturbing. I've played every genre from Classical to Classic Rock and simply don't want to shut the amps off. Even after several hours of moderate level listening the transformers are simply warm to the touch. The bass response is incredible, the extra capacitance was certainly worth the investment.
The sale is for the two MKIII amps, the tubes, the covers and the manuals for the amps.
