Dynaco ST-70 Stereo Tube Amplifier. Completely Restored. Excell Working Cond.

Description

Here is a restored Dynaco ST-7 tube amplifier. I bought it from the restorer himself, and had used it with satisfaction for several years until I upgraded to a pair of restored Dynaco Mark IV’s a few years ago.
Below is quoted from the original restorer:
“A restored Dynaco ST-7 stereo tube amplifier. Chassis was stripped of all components, re-sanded, and finished with 5 coats of satin black epoxy coat. Restored with new AE and Xicon power capacitors with nearly twice the supply capacitance of the original. Completely rebuilt bias network of value/rating bias supply caps and new matched resistors. Modern diode replacement of the original. PC-3 driver board was completely stripped of all old resistors and caps, cleaned, and re-stuffed with quality modern matched parts. Rear panel has new heavy duty gold plated 5-way speaker binding posts, new toggle pole. Has original Dynaco PA 060 and excellent ZT326 output transformers. "
Equipped with two vintage Raytheon 7199’s, one vintage Sylvania 5U4GB (instead of 5AR4) as rectifier, and a matched quad of JJ Tesla EL34/6CA7’s, the amplifier works and sounds with clarity and good sound staging. A good set of vintage EL34’swould further improve the sound quality.
No international shipping. Please note that there is only one connection to the speakers, namely the 8-ohm connection. That means the amplifier performs optimally for 8-ohm speakers.
You can return the unit within a week if you are not satisfied with it, though you’d pay for the return shipping cost.
