Steve, i have no idea if Preston Nichols Time-Travelled or not, what i do know is that he bought a huge amount of SBT`s with a view to making a Time-Machine...Obviously there would be other circuitry incorporated that would be needed in any Time-Machine, such as an extremely stable Delta Time Generator for navigation purposes..
Yes Steve, Germanium is supposed to contain faster than light Tachyons, although i dont recall Preston Nichols mentioning them in relation to a Time-Machine of his, although i could be wrong...IMHO, the Germanium SBT`s would be partly used in an electron tunnelling function, just the same as the DTG in this thread..
I dont see why any frequency doubler would be necessary, when all the frequencies that would be needed, are already within the SBT`s frequency range...Even IF higher frequencies were needed, they would come from the harmonics created by the SBT`s.. Remember Steve, the DTG is basically an oscillator that naturally produces harmonics..
Iam really pleased to know you have read the book, The Music Of Time...Perhaps you might be interested in the other Preston Nichols books such as, The Montauk Project, and the Montauk Revisited, book...Germanium Transistors were developed from the Germanium diode Steve
