The ST-35 became famous amongst the audiophiles for its fantastic iron. The output transformers were the famous

Z 565. Some people believe that this iron was the very best that Dynaco ever produced. Some believe that the

transformers were even better than the famous A 470(454326) transformers in the Dynaco ST-70. 

Considering the ST-35’s small size, it is amazing at the sound that this amp can produce.

 

The 1964 Dynaco brochure lists the intermodulation (IM) distortion at less than 1% (each channel) for 17 watts.

At "average listening levels" the IM distortion is listed at below 0.1%. This is very good for a tube amplifier.

 

 

What is so remarkable about this amplifier is its very small size. It can easily sit on a book shelf which is convenient

if the amp is driving bookshelf speakers. It can be hidden out of the way if need be, but it is so cute looking that you

may want to show it off! The EL84 tubes generate less heat than EL34 tubes so the ST-35 runs cooler than its

bigger brother.

. The earliest output transformers have the number Z 565 stamped on them. These transformers were hand wound

in the USA. Later versions were manufactured in

Japan and were machine wound. Eventually the part number was changed to 454565.

The earliest power transformer was made in the USA and had the part number PA 774.

Later versions were manufactured in Japan.

 

Dynaco has a unique history because the founder, David Hafler, had originally co-founded Acrosound.

This company became famous for its tube transformers. Eventually, Hafler parted Acrosound and created Dynaco.

It is not surprising that Dynaco had very special and unique output transformers in it amplifiers considering that

Hafler had the knowledge to create these very unique transformers. So Dynaco, despite being relatively

inexpensively priced compared to other amplifier manufacturers, had very special transformers in its products.

This fact is not that well known. Some people purchase old Dynaco amplifiers for parts just to get at those special

output transformers - heresy! 
 

The ST-35 has a wonderful sound with fantastic midrange response. The human voice in singing comes through

very smoothly. The ST-35 really shines in the midrange. The midrange is exactly where the human voice is

positioned on the frequency scale. So although bass response is subdued, midrange come through almost lifelike.

Even more so than in the ST-70. The sound of the ST-35 is sweet and smooth. It is mellow and laid back.

"Easy listening" are two words which aptly describe the personality of this amplifier The volume capability was less

than the ST-70, but this was expected since the ST-35 is rated at one-half the wattage of the ST-70. Nonetheless,

there was sufficient volume to fill a medium size living room, and even then the volume control was set at only the

twelve o’clock position.
