First RF test and found the tune variable capacitor totally meshed out, then I removed few plates and measured the capacitance is in between 4.5 to 10 pF. The tank coil also cut one Turn, now is 3 turns. The load capacitor is half-meshed, just fine.
After that, test Starting with 5 W of drive from a TS-600, gave 85W on the output first time, which equal to about 12.3 db gain.
Increasing the drive up to 10W brought 150W output, equal to 12.07 db gain.
I stopped at this point because the 150W dummy load already very hot, will test later with a high power one.
I also installed the top cover with ventilation holes.
