Re: help!

Hi, I wanted to thank all the guys who answered me to try to help me  
solve problems with a rotoverter. The variac has arrived, but even if  
placed at 1/4 of the current foreseen in connection to Y, the thing  
does not change, the rotor turning without load heats up, the current  
consumption is low, about 0.5 amp. which increases if the capacitor  
microfarads increase, and the power is low .... the only doubt I have  
left is the capacitors ... they are the normal ones for AC that they  
sell in electronics stores, and not the old ones in oil bath ...  
that's the problem ...? Has anyone ever done the same?
