Dynaco ST-70 with Van Alstine “Ultimate 70″ mods. This is a legendary amplifier and a piece of audio history that’s been modernized by Frank Van Alstine. The mono/stereo switch has been removed, input and speaker jacks have been rewired and replaced, and a heavily upgraded circuit board has been installed. Current output tubes are Psvane EL34B; Cosmetics are 8/10 due to some rubbed off lettering on the chassis. I live in suburban Portland, Oregon. Problems are few, and I’m very pro-active about solving any that might crop up. Please examine the pictures carefully. They are part of the description. This is NOT a new component. As such, it does not come with any guarantee– implied or written. Vintage audio equipment is sensitive and does not travel particularly well. So in rare instances, that which was working 100% at my house may require adjustment or servicing before working equally well at yours. Most on-line sales of vintage electronics happen under these exact same conditions-but I just wanted to point this out so there are no misunderstandings or disappointments. Spoiler Alert: They will NOT allow this. But please understand: I simply clicked a box making this available to International buyers. Here are a couple that my International customers have successfully used in the past and have a good reputation: Nippon Express USA or U. Both are located in San Pedro, CA. Contact info is available on-line. I’m looking forward to doing business with you and earning more of it in the future. I absolutely LOVE this stuff, and you will find me to be a reasonable, fair-minded person to deal with.

For sale is a vintage. Dynaco SCA-35 Tube Integrated Amplifier with Phono Stage. All tubes are vintage tubes; some of them are Dynaco. All tubes are included. Dynaco SCA-35 share the same transformers with the highly coveted Dynaco ST-35 power amp. As shown, the transformers are huge. This amp works and both channels produce good music.

Vintage Dynaco ST-70 Dynakit Stereo 70 Tube Power Amplifier It is untested – NO TUBES. THE TUBES ARE NOT INCLUDED.. I bought this to use myself but have since bought a pair of mkiv. And then they stopped working. There is a burnt out resistor and another one that is cracked. I bought the resistor to replace it but never got round to it. I understand a lot was done by way of modifications including the meters and the individual test points for each tube and adjustments. It’s a beautiful amp and I’m sure it will give the new owner good sound once fixed up. I’m including the new and old resistors and also the old driver board.
