I "burned up" an LDG Z11Pro II. I put too much wattage through on 6 meter FT8. Apparently it should have been less than about 30 watts. I used 100. It would not tune. A buddy opened it up. At least 2 of the toroids were 1/2 black (heat) and a relay was blown. He replace the relay and it now tunes, but I cab" put it into bypass.
Don't know if this helps, but you aren't the only one to injure a Pro II.
