Hi guys. Does anyone know how to de-tune trimmer capacitors. They are variable capacitors and can only be manipulated on the PCB, they are not for the end-user only the technician. I want to build a working RPX device. I am buying an RPX device with Multifunction generator and lithium iron battery as a package off A&PMedia or whomever is behind the Bedini team, to support their research etc. But this 1 issue is confusing me. I am untrained at this point and I have taught myself beginner electronics, but at this point this particular issue has stop me in my tracks for now at least. Any help would be most appreciated. The trimmer capacitors are part of a (PI ?) network on the circuit and according to John Bedini they have to be "de-tuned". Many thanks. Pat.
