    Photos of the new Dynakit ST-70 I built

    A new customer of mine wanted the sound of an original ST-70 but didn't want to buy a used ST-70 of unknown origins so he purchased a Dynakit ST-70 kit from Kevin at Dynakitparts.com and had it shipped to me to build.

    I must say they way Kevin packed the components in individual bags with labels and supporting documentation, it makes it real easy for a novice to build the amp even if he has no concept of electronics but can follow directions.

    Here are 4 photos of the ST-70. I tested the amp with the 6GH8-7199 adapters as you can see in the picture but my customer brought his own tubes including 2 NOS Dynaco 7199 tubes that I installed when he picked up the amp.

    You can see I installed the BBCU-1 Bias Balanced upgrade also. The printed circuit board is the original color Dynaco used back then, I installed Orange Drops capacitors as the customer requested it from me although the coupling capacitors that came with the kit are of high quality.

    Sal,

    Solid build and I appreciate you taking the time to post the photos. I'd love to hear the more original (non VTA) amp just to hear it.

    Question - Where did you get the speaker terminals you have on that? I have a single Red and Black and I'd have to de-solder / solder the wire if I made a switch from the 8 ohm speakers I'm running now...

    Thanks man
    Andy

    Thanks Andy,
    To my knowledge, Dynakitparts.com is the only company that sells the 4 terminal Banana speaker terminals.
