Spring 2015
Welcome,
This page is a place holder to share my interest in vintage style, relatively low power, tube based hifi amplifiers.
The primary focus will be on Dynaco's two smaller amplifiers; the ST35 stereo and SCA35 integrated units. First produced in 1963 and 1964 respectively, these amplifiers were available as either factory assembled units or DIY kits priced between $80 and $120 at the time. Both units were designed around the relatively sweet sounding EL84 power tube and are rated at 17.5 watts per channel, almost laughable today in a world of high power 7 to 9 channel receivers and amplifiers.
Despite being some 50 years old, and with modest power output, the smaller Dynaco amplifiers produce a wonderfully warm and musical sound that compliments today's modern digital music sources. In fact, Dynaco's musicality coupled with modern digital convenience are likely a combination 'greater than the sum of the parts', especially when the human voice is central to the music program.
In addition to producing great sound, the opportunity to assemble a unit oneself brings another level of satisfaction to those that are so inclined. In any case, the Dynaco ST/SCA35's musical performance, longevity and construction simplicity serve as compelling testimony to the enduring strength of their original design and engineering. This supposition will be more fully explored as this site is further developed.
The vendors noted below each provide excellent products and advice to help build either of these great Dynaco amplifiers.
