[R-390] R-392 connectors

[Jon & Valerie Oldenburg]

The LS-166 will always sound poor due to the weatherproofing of the speaker.
Open it up and replace the speaker if you wish to use it. A better fix is
the use of a Radio-shack PA 70 volt to 8-ohm transformer and then use your
speaker of choice,  the Radio shack  small meal cased speakers have real
nice fidelity. Jon AB9AH
