The partnership of David Hafler and Ed Laurent in 1955 gave birth to one of the most influential Hi-Fi audio companies in the world. Like other audio component manufacturers of that day, Dynacos objective was to produce components capable of the finest sonic reproduction, although unlike anyone else they strived to make these components affordable to the masses. Prior to Dynaco, Hi-Fi components were only obtainable by two kinds of people, the rich and the super rich. Dynaco did sell preassembled components, although what set them apart was that they also sold these same components in kit form. Much of their success was due to these kits. Consumers could afford the highest grade components, yet shave off much cost by assembling it themselves. This method was extremely successful. Dynaco set a string of sales records that still remain unbeaten today. The biggest selling; preamp, mono tube amp, stereo tube amp, solid-state preamp, solid-state power amp, are all records still held by Dynaco today. It is no coincidence that these sales all took place in what we refer to today as the golden age of audio, in-fact it is safe to say the components Dynaco produced in that era have a lot to do with why we call it the golden age. The many Mark and ST series tube amps and PAS preamps, all have earned classic status, and they have introduced more people to hi-fi audio than any other.
In the late 50s while David Hafler was out of town on business, chief Dynaco design engineer Ed Laurent and his associate Bob Tucker got the idea of combining elements from Dynacos highly successful MKII & MKIII mono amplifiers onto a single chassis in a stereo configuration. By staying true to Dynacos philosophy of minimalist circuit topology and high grade components the two engineers efforts resulted in what later became the best selling and most successful amplifier of all time. A title the Stereo-70 still holds today.
Obscured by the fan-fare of the ST-70 was a little gem, that many feel was the best amplifier Dynaco ever made, the ST-35. Even today few know about the ST-35 and it is the least recognized tube amp in Dynacos history. With a 17.5 watt per channel output it was easily dismissed on paper, yet the few who took the time to auditioned it found they were the sweetest watts imaginable, and a perfect match for the many high-efficiency horn systems of the same era.. Secondly, the 17.5 watt per channel rating was a very conservative one, as the ST-35 has been tested to deliver more than double that amount in actual use.
The ST-35 has Z-565 output transformers, which are highly regarded for their extended frequency response and amazingly low distortion levels. These perfectly compliment the El-84 output section. Sonically the ST-35 is a dream, its midrange is pure honey, sonically projecting a vivid and accurate soundstage, capturing instrumental timbres and voices with a degree of realism that so many of todays amplifiers miss altogether. Its overall sound is alive, dynamic and thoroughly musical. The ST-35 is truly one of the last hidden gems of golden age, it outperforms many of the mega dollar classics from companies of the same era. The ST-35 is a true powerhouse that will only gain in popularity, and price, as more and more audiophiles discover its greatness.
