    st70 current draw

    Post by corporalspiffy on Mon Jun 08, 2015 7:34 pm

    if i was to use a multimeter to read the current draw of an st70 what kind of reading will i get?
    if i install two amp meters in a variac project one reading 1-10 amps and the other milliamps would these be wired in series or parallel?

    This makes it easy: http://www.p3international.com/products/p4400.html

    It's been a while since I checked my Stereo 70, but I think the quiescent current draw was less than 2A - something like 1.5A.

    ST70 uses right about 1.5A. Simple ohms law, next to the AC power plug on the back it says 175w (175w/120v=1.5A) the manual says 190w max.
