Another Class C Cb
competition amp with no bias or filtering.
BBI 370 Peak
BBI 105 AVG
X force 390 Peak
X force 120 AVG
X force is making more power.
Without a current meter you can not tell how many amps they are drawing, but it looks from the vid that the BBI Amp is pulling the supply down more than the X force, drawing more current?
What is that extra current doing?
Not seeing it on the wattmeter.
Making more heat?

Not a true peak reading wattmeter, uses a passive capacitor added to the meter to provide a peak reading.
How is he telling it is making harmonics, I did not see a spectrum analyzer anywhere on that test bench to tell anyone that either of the amps are spewing anything.
Not even a scope.
What is the price difference?
Lots of questions that need answered.
I will say that the example shown has nice soldering on the board.
