Complete set (2 Z565-48 output, 1 PA774 power, & 1 C354 choke) Great for the DIYtube.com ST35 project. Check out our st35 chassis as well.

Z-565 Output Tansformer: Upgrade and replacement for the original Z-565 found in Dynaco (tm) Stereo 35 amplifiers.

New unit made in Chicago,USA by transformer professionals with decades of experience manufacturing high voltage transformers.

A reproduction of the Dynaco Z565 output transformer as used on the Dynaco (tm) ST35 and SCA35 amplifiers, except that the output taps are 4 and 8 ohms, rather than the original 8 and 16 ohms, thus making this transformer useful for many do-it-yourself projects where an original Z565 can't be used due to its lack of a 4 ohm output tap. The primary is wound the same as the original 565, same number of turns, sections and wire size, using the same patented Dynaco winding method, and made on the same core size and material. Only the secondaries have been adjusted to accomodate the different taps, and improved insulation material used (thus making the transformer more resistant to abuse). This transformer has what you'd expect out of a Dynaco transformer, like healthy low frequency inductance (over 1000 henries at 60 Hz), high resistance to distortion caused by output tube imbalance, and low distortion overall.

There are plenty of neat DIY projects one can build with these transformers, such as the one at www.diytube.com
These types of transformers can be used with many tube types, such as 6BQ5/EL84, 6V6-GT, 6AQ5, 6BM8/ECL82, cathode-biased 807, 6L6, KT66, 832  and others.

Transformer specs are:

8000 ohms CT primary with screen taps, 4 & 8 ohm secondary.
20 Hz to 20 KHz response at 17.5W, within 1 db (30-15 KHz @ 35W)
Max DC per side (suggested) 80 ma.
Height 3 inches (75 mm) width 2 1/2 inches (63 mm), depth over covers 3 1/4 inches (80 mm), mounting centers are 2 inches (52 mm) by 2 1/4 inches (55 mm).

PA774 Power Transformer: Direct bolt in replacement-no drilling or cutting required to install.New unit made in Chicago,USA by transformer professionals with decades of experience manufacturing high voltage transformers.
Guaranteed to meet or beat published specifications for the original Dynaco part. 

Runs cooler, regulates better than original due to improved insulation technology that allows larger gauge secondary wire, resulting in about 25% less copper resistance on the secondary. Secondary is 330-0-330VAC at 180 ma DC rectified current, plus two 6.3V at 2.5 amp windings for filaments & pilot bulb. Primary is 120VAC 50/60 Hz. Measures 3 inches (78mm) high X 2 1/2 inches (64mm) wide by 3 7/8 inches (100mm) deep over end bells. Mounting hole bolt pattern us 2 inches (53mm) by 2 3/4 inches (70mm). Ship wt 5 lbs (approx 2.2 kg).
Great for homebrew \ DIY projects. Some regard the ST-35 as the best of the line.
