Does anyone have any experience using sound powered headphones with a tube
radio?
They're prized by crystal radio builders for their extreme sensitivity. I
have a pair of "deck talkers" and have wondered how they would work with an
R-390/392 or even a one tube regen set. If I'm not mistaken, the impedence
is a bit lower, something on the order of 100 ohms, so they would require
some sort of matching network.
Anybody have experience with this?
Thanks,
