The same guy that has the dc PSU has variacs very reasonable. If you want a link I'll get if for you. I know a couple of you said you wanted one.

Get one with at least a 10 amp rating, and they don't do inrush. I'd forget while had the 700 on the variac with it sitting on 100% and take out fuses.
 
hARD TO DO WITHOUT THEM, PLUS THEY'RE FUN TO MESS WITH jANI, i'VE DIMMED THE WHOLE UPSTAIRS AT TIMES, DEPENDING ON HER CONDITION IT WAS HILARIOUS OR TIME TO LEAVE THE HOUSE.
 
I don't recommend those for 2 reasons. First, with today's switchmode power supplles, you need bot isolation and a variac in one unit, or you will melt your expensive scope probes. Second, you need a current meter!
Look for used Sencore 1655 or even better, Heath IP-5220. You only need a 3 amp (375 KVA) to repair audio.

Why would you put a SS unit on a Variac? Monkey :D
 
With a Variac in series with DBT(dim bulb tester) you can limit VOLTAGE and CURRENT, a VERY good thing sometimes. Nakdoc, if I work on something with a SWPS, I'll be lost anyway.
