You asserted that nanotube resistors are noiseless..

You are incorrect..face it..the authors you cite point out specifically what is going on..

It is unfortunate that in physics, there is no free lunch. It would be fantastic to have noiseless resistors, so I can easily understand how a designer such as yourself would jump all over those possibilities..

But, ya missed the fine print..hey, your human also, just like me..ya gotta live with it, admit the error, and move on..

If you REALLY wanna do something, listen up...

Take a vacuum tube you would normally use for low noise low level signals, and have the cathode coated with nanotubes..with a process that has them standing up. This would be an integrated cathode resistor..it would indeed be noiseless, as the ballistic electrons would release at the vacuum end, so the joule heating caused by impact on the terminals does not occur, rather, it simply adds to the energy the electrons have when they hit the plate..

And, as an added benefit, I believe it may also require less heating to emit electrons, as the nanotube size may be sufficient to pop electrons into the vacuum...kinda like the etched emitters they have been working with on the flat panel displayes.

It'd be a new, novel product..it be tubers, it be neat..it would also be a nitch product, so it meets darn near all the requirements of esotheric (sp?) audio.

As for noise spectra? This would have been a perfect opportunity for you to show off your capabilities..explaining to us how the spectra compares to that of a normal resistor...you, instead, feebly attempt to use a question to assert dominance over another..this is a sad thing, really..not becoming of anyone with intelligence...

Think about acting civil, won't you?

Cheers, John
