You use to use both the F165 as a pad device and simultaneously use your 10 million Hz Plasma device by Rife labs. You liked the Rife Labs device better than the Perl (Bare/Rife) plasma device.
So now your using the F165 to power and control the ABPA A2 Advanced Bio-Photon Analyzer. And you say the sub space device works much better than anything you have tried.
I guess it's more than possible that the ABPA A2 Advanced Bio-Photon Analyzer could work. We know by quantum physics that everything is connected someway.
I would say the F165 is the first thing to get as you can use it by its self as a pad device. Then later add on.
The GB 4000 is an impressive machine especially with its added amplifier. The F165 is much less money, by default uses a positive offset square wave and is used by many professional.
