GE Superadio III awful with headphones

Post by lthanlon »

A relative recently gave me a General Electric Superadio III that she found at a church rummage sale for $15. The radio is in mint condition and came in its original box. I wouldn't characterize its AM DX abilities as especially super, although it does pull in a fair number of distant stations, especially after dark.

The two speakers produce excellent sound, but when listening with headphones or earbuds, the background hiss makes serious DXing impossible. (Late at night, I need to listen with headphones to not disturb other members of my family.)

I've never owned or operated any Superadio models before; is this headphone-hiss problem typical?

According to this thread

this could be a general problem with them. Alas there is no remedy listed, also not on this site with modifications:

High impedance headphones could mitigate the problem a little as an easy option, particularly if you use 8 Ohms cans some 32 Ohms or higher could help.

aside from modifying the radio,. I wonder if a simple external audio filter may be of help

Thanks for the ideas! I'll look into higher-impedance headphones.

Anything that allows for turning up the radio's volume (to lift the audio over the amp's noise floor) and reducing it on the other side will help.
