I've been looking around for a Variac and I've noticed that while all of them
run around 0-140 volts they have widely differing amp ratings. How large of
an amp rating do I need for TC use? I know that I could just look on my
xformer and see that it draws 2.2 amps and use that as a guide but I plan to
get an NST to replace my OBIT soon and I don't know how much current they
pull. Will a 5 amp variac work or do I need to go with the larger 30 amp...or
is there somewhere in between that would be more suitable to TC use?
Left, left, I hadda good brain but it left...
