Got a free Variac today
« on: October 14, 2017, 05:50:14 pm »
I was given a Powerstat Variac today!

0-140v, 50-60hz, 7.5a max, 1kva max

My question is, "is 7.5a adequate"?

thanks

Let your line fuse be your guide. If the fuse is rated for more than 7.5A don't plug that device into the variac. If the fuse size is less than 7.5A, safely plug it into the variac.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thanks Sluckey!
That's what I was thinking but, never having used one before, I just wanted to make sure I wasn't missing something.
