Dynaco (Dynakit) Stereo 70 (ST-70). Vintage Stereo tube amplifier. Serviced: cleaned and vacuumed chassis, cleaned all controls and switches, and jacks. Tested all tube outputs. Installed replacement 7199 tube. Replaced fuse, connection at fuse holder and set bias. The Dynakit Stereo 70 is a complete dual 35 watt power amplifier kit which offers the highest possible fidelity, at low cost and in a compact arrangement. It uses a patented circuit of outstanding performance characteristics, along with top quality parts, including the new Dynaco Super-Fidelity A-470 transformers – the finest available. The measured specifications show that the Stereo 70 is an amplifier of unequalled performance, and its listening quality is also unrivalled by any regardless of price. The two non-interacting 35 watt channels provide adequate power, in a stereophonic or two channel system, for loudspeakers of any level of efficiency. The channels can be paralleled for a full 70 watts of low distortion output, suitable for practically any monophonic use even where several loudspeakers are in use in different areas. The high power capability and low internal impedance provide excellent damping for all types of high quality speaker systems without need to make adjustments to match specific speaker installations. The design features of your Dynakit which contribute to its superior listening quality include some which are not revealed by the customary steady-state laboratory measurements. For example, it does not exhibit bounce and flutter when pulsed with a transient signal. Thus a sharp percussive signal like a drum beat or a piano note will be reproduced with sharpness and clarity and neither overhang nor muddiness. The Stereo 70, unlike many other amplifier circuits, has been designed to provide its specified performance on a loudspeaker load, not just under laboratory measuring conditions. Therefore, the connection of a loudspeaker to the amplifier does not deteriorate its performance or listening quality. AS-IS sale due to age.

VINTAGE Dynaco ST70 Fully Working with DYNAKIT with Mod

Original Dynaco Dynakit Stereo 70 – Fully Working with Mod. Our loving office amp has been replaced. Fully working and has been reliable for 6 months. This ST70 has served us well. Very lush and full bodied sound. Seems to have original driver board but it looks as if there was a mod made at some point that added a daughter board. It may also have something to do with the missing mono/stereo switch. Overall condition is very good for its age. Some patina on the metal but probably can be polished. Some harder to get off dust but generally pretty clean. Grill is in great condition with only a couple minor paint chips. The mono/stereo switch was not installed and runs only in stereo. This can be fixed with parts orders online. Please note with any vintage electronics that there is a chance that a part might fail or need replacement. This has been reliable but you never know. Plenty of manuals and info online in the event you need to replace a part down the line. Please message me once you have made ordered the item. Great amp as is or fantastic restoration piece.
