SWR High with the amp off

I am running a station 550 and an anytone 6666 all of a sudden my swr is over 4 when the amp is off 1.2 with the amp on and 1.0 with the amp completely out of line. Anyone have any ideas?
 

That quad 6 is a hot radio too, not sure what the pass through wattage is on that amp. You could have toasted something with too much powa.
 
Either the contactor pads on the NC circuit in the relay are arced or the capacitors for the tune have lost their value or come lose, I'd go with the later myself. There's not a whole lot going on during the pass through operation.
