That or a choke with enough inductive reactance to drop the voltage as that's all a variac is. Put it in the primary side and figure for the current drawn through it to size it. Best, Will ** REPLY S

Bill, It's according to how you hook it up. If you connect one end of the variacs winding to the line, and the output to the wiper (going to the load), leaving the other side of the variacs winding u

Rich, Isn't a choke an iron core with one coil on it? What if we put a tap on the choke, that's the same at the wiper on the back, only it moves from coil to coil. One could say an autotransformer is

I need to clarify one thing I said below. That doesn't mean adding a variac set up as a choke to the secondary HV side, it means to use a regular choke. I don't think I'd want to handle a variac with

For relay contacts, you can try some of the chemicals by GC Electronics. The old way is to use a contact burnisher which GC makes also. The last way I found was to use CLR. That's right, CLR from the

Let me make a correction on the size of toroids they've been using. Instead of 1/4" thick, they used 1/2" thick, 1/2" OD, and 0.3" ID. Palomar number F-50B. 1/4" thick is almost as much in price as a
