How to use the Variac in this situation have to bring up the voltage but when you bring it up to the operating voltage it blows the fuse so what does a tech. do in this situation?

If i use the Variac at HALF the voltage then the output of the power supply and regulator is going to be HALF B+ supply voltage so how do i know whats drawing to much current? thats blowing fuses?

If Changing all the power Transistors and it still blowing fuses and drawing to much current what would be the next this that is drawing to much current and make the fuses blow?

The Regulator being open or shorted would cause this?
A Filter Cap in the power supply would this cause this?

How do i use the Variac to track down the current draw? and flow blowing?

Hi! You can use the following to start trouble shooting

Although the article was intended for a Marshall Valvestate, the Power Supply section is similar...if you face any further challenges, feel free to contact.
