Default Favorite Headphones Question

ABSOLUTELY on the Sony MDR V150 for modern radios.

But the BEST headphones for shortwave listening which I have EVER used
(and still use occasionally) are the Clevite "Brush" Crystal Headphones
Model BA-200. They have restricted frequency range to minimize static
and hiss, and overall clear and bright sound up to about 5000 Hz. When
you can't "read" a signal through a loudspeaker, these come to the
rescue! Unfortunately the impedance is so high (45,000[!] Ohms at 1000
Hz) that the volume is greatly attenuated when using them with modern
radios. But used with my old Lafayette HE-10 (or any other classic tube
receiver), they are tops. And I mean TOPS! I bought mine in July 1962
and they are still as good as new!

Best,

Joe

Try using an audio output transformer, plate to speaker, in reverse.
Should
give you quite a boast on the audio level with no ill effects. It might
be a good
idea to put either a 10K pot oo a 1 to 2 K resistor in series to help
control
any low level background noise common in most recveivers.
