useing a Variac to test radio
#2

Hi All;
Warren, I would not just up the voltage just to see if something smokes..
When, I use my Variac, for the first time on something, I also put in the Dim bulb as well.. Also, I would with each upping check the different voltages, to see if they look like they are in the appropiate ball park of what I would expect.. I start at about 40% and check my filament voltages and B+ voltages, the got to 60% things should have a readable value by then.. then upping 10% at a time untill I get to 100% then by 5% untill It reaches about 115%.. By that time all readings should be in the range of what I would expect from the schematic.. If things look ok by that time and nothing is way off, then I can remove the bulb.. And only use the Variac.. But, If at any time things are not looking right or correct I would immediately shut things OFF.. And Investigate what is wrong..
THANK YOU Marty
