Vintage Dynaco Dynakit Stereo 70 ST-70 Amplifier Tube Amp & Cage – Mullard Tubes. Fully tested and 100% functional; this classic will add that warm tubey goodness to any home stereo hi-fi set up. Tubes are all excellent. The tube complement is all Mullard – 4 x EL34, 2 x ECF82 and 1 x GZ34. The speaker posts were upgraded by the original owner to banana jacks. In doing so the 16 ohm output has been disabled. The RCAs look to have also been upgraded. Cosmetically, it is overall very good exhibiting only normal wear from over the years. Includes original cage (one screw for the cage does not match). Also includes a copy of the manual/schematic.

Consider that if you have an allergy. Everything pictured is included, no screws for the cover.

I bought this piece all dusty and without been used for years from a garage sale a few years ago, it had one broken tube. I’m adding pictures of the old capacitors, the old tubes (two are MULLARD Fat Brown base EL34 Xf1 still good and the other two are old xf2 black base EL34 tubes), the receipt for the service and a Manual I print out.

Dynaco ST-70 unbuilt kit. Original Dynaco Mullard tubes. I will protect the amp well. Tubes will be boxed separate do forces dont smash them. Cabinet shell has a few minor bends due to its travels.

Offered is a Dynakit 70 Stereo. I know very little about this. The stereo system was left hooked up in a investment property I acquired. Seems it was kept in pretty good shape. It was still hooked up to speaker wires and a turntable when I found it. I cannot speak on its functionality. I did plug it in and all of the tubes lit up. With my lack of experience, you should figure it for parts or in need of repairs. Feel free to ask any questions and I will do my best to answer.

Lot of 2 pieces of audio gear.. It is a great addition to any collection of vintage electronics and would make a great project for those who enjoy restoring or repairing vintage audio equipment. The amplifier is a classic piece of American engineering, made in the United States by Dynaco. The amp is a Type: Tube Amplifier with model number ST-70 and has not been modified. It is perfect for anyone who appreciates vintage audio and is looking for a new project.
