I looked at Parts Express and I see three models: 3A, 5A and 10A. The Stereo 70 in its stock form takes a 3A fuse (don’t use a larger fuse in the Stereo 70 with the original power transformer). If you don’t ever have any problems with your Stereo 70 that causes its fuse to blow, and if it is all you might ever variac, then the 3A variac should be enough. However, if you ever do have any problems with the Stereo 70, then you might blow the fuse on the 3A variac, not that 3A fuses are expensive.
If you think you might ever want to variac anything else that might draw more current, then the 5A or 10A models will give you more leeway.
