Base price per pair is $2,650.00 before adding options and tubes

This is the special order MK III. The base price shown is for a single amplifier without upgrades, options or tubes. The MKIII is a single channel (MONO) amplifier producing 60 watts. Used as a pair, one per channel, this will create a 120 watt stereo tube amplifier. The MKIII amps sound absolutely stunning!

These Dynaco MK III (MKIII) amplifiers are custom built and can be tailored to your liking. These will have a 3-4 week production period, It takes some time to order and assemble the components, and of course time for building and testing the unit. Usually there will be a few orders to complete before I get to your build. The component varieties, brands and features offered are proven top performers. You can "pick and choose" from these options with confidence for a great sounding amp.

The photos shown are of previous units with options and upgrades, to provide visual examples. Generally speaking, most units look very similar when completed, but your specific unit will have all the special features you have chosen.

about the Dynakit MK III Monoblock

Beyond great build quality we go even further, to assemble a complement of high performance and reliable components to ensure the performance and sonic capabilities of these amps. (photos show several different sets of amplifiers from previous builds / customers and may reflect use of different components than described in the ad)

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. Simply the ultimate in stereo separation and realism, the monoblock amplifiers deliver the music like nothing else can. One of the very best mono tube amplifiers ever made.

These MK III amps feature 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. 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. 

Each amplifier has a genuine Dynakit C-354 filter choke. These are fully encased in a metal housing for excellent shielding and won't leak and goop up your chassis like the old design could. The C-354 is varnish dipped for moisture resistance, improved electrical insulation and reduced vibration.

Each MK III circuit board is a stock Dynaco PC-1 using the original circuit and a single 6AN8A tube. 

The standard build features CDE (Cornell Dubilier) 940 Series Capacitors for outstanding sonic performance and reliability. 

The resistors used in the standard build are carbon films in the audio path and metal film/metal oxide in the power circuit for superb accuracy while retaining the warmth and even order harmonics so desirable in tube amplification. Even order harmonics are favorable to the western musical scale and are more pleasing to the ear than the harsh odd order harmonic distortion created by transistors.

The bias and power supply features 100uF 100 Volt rated electrolytic capacitors for outstanding electrical performance.

All of the wiring is 22 AWG USA made stranded wire and is carefully and properly routed and secured in the chassis. 

The amplifier incorporates the original bias circuit and traditional adjustment pots. You can upgrade to the bias balance control for more accurate and balanced tube biasing.

Standard pricing includes original style screw terminal speaker jacks for 4Ω , 8Ω  and 16Ω  ohm loads. You have the option to upgrade to barrier blocks if you like.
