Jeremy, OK, Q7 and Q8 are 'toast', you might as well remove them.
With Q7 and Q8 removed, do a TUNE and measure the DC voltage at the solder pads for the base of Q7 and Q8. The expected voltage is 0.60 to 0.64 volts. If it is out of that range, replace Q11 and Q13 too. Those transistors come included in the K2PAKIT.

Q7 and Q8 both read 12.3 ohms from collector to ground. The symptoms definitely resemble blown finals, as I experienced the same thing when I was building the kit, including the over current tripping the resettable fuse. I just didn't expect that from a receive only condition. Jeremy VA3ZTF
