My first stereo system was literally built around a Dynakit ST-70 in 1966. Over the years I've owned a few more used examples, the most recent one now under Rod's care and feeding. So from time to time I enjoy reading what others are doing with this classic.

Thanks Josh and others for posting your experiences here. As a current owner of the Don Sachs version of the VTA SP-14 I'm a fan of the 6SN7 as well.

A 6CG7 could be used... - 1973shovel 09:09:23 04/03/23 (4)

Would that be easier than just replacing the driver board with the VTA Octal one? - JoshT 09:14:27 04/03/23 (3)

It would certainly be "easier" from a physical labor standpoint - 1973shovel 09:53:40 04/03/23 (2)
