I bought this wavetek at a great price and before powering it up I look inside. I found the varistor "VR1" had burnt out severely and left a coat of black smoke film on the PCB and the back plate.
What could have caused it to burn this bad and what other components could have been affected by this.
I will clean the area first and look for any signs of over heating and damage before doing anything else'
I bought a new replacement for the varistor P/N V56ZA8.
What do you guys think. Your input is greatly appreciated.
