A proper restoration must replace all electrolytic, paper, film, oil capacitors. Do not fall for partial kits. A proper rebuild requires a full recap of all oil, paper, lytic capacitors. In 99% of the cases, only a few parts were replaced, instead of a full and proper restoration job.

This kit will update one ST-70 or SCA-35 amplifier, or 2, Mark II, III, IV or Heath-Kit W-4 mono-block amplifiers, one Marantz 8B amplifier or one H-K Citation II amplifier. Sorry, but these will not fit the ST-35 amplifier.

Dynaco ST-70 tube amplifier with upgrades! I installed bias balance pots on this amp. Now you can balance each tube independently! They are located in the center of the front octal sockets. I tried to show it in the pictures.
