    Hi All,

    First I figured that someone much smarter than me would have done this already. My suspension is that I am about to be told why you can not put a switch in here. I was looking at a way to not have to pull apart the ST-120 when switching rectifiers between tube and solid state. Will this work? I was thinking the power on the back end of the relay will go nowhere once it hit the open end of the switch. What would happen if I did this? Thanks Scott

    I did this and it works great. I chatted Bob first and he said it would work. He was right!
