Greetings to the group, and thanks Nick for your information on the switch.

I can use some advice.  The 600L that I have had on the air for about 3 years now (thanks to some help from K5EF) has suddenly developed a problem.  I can turn the Filament switch on with no problem.  But about one second after I turn on the Plate switch, a relay throws and the Load Mismatch light comes on.  I can make it go off by pushing the Plate Overload button but the light is on again as soon as I let go of the button.

I think I caused this.  The other day, I failed to notice that I had left the plate switch on when I turned on the filament switch.  I have had this problem ever since and the amp is off the air.

I assume I will be pulling the front panel (again, as I did when I first put the amp on the air).  

Do yall have any advice as to what I should be looking for?

Thanks, Lynn, K5LYN.
