George, I believe that guidance you heard referred to the very old radios, not forties or fifties stuff. I think if you take an ohmmeter and measure the resistance of the originals, they're going to be between 4 and 8 ohms (my '47 Hudson original radio had an 8 ohm speaker). Find some 6-8 ohm modern ones that fit, and you'll be fine. Park Waldrop C cpe - Atlanta ------------------------ Yahoo! Groups Sponsor --------------------~--> Help save the life of a child.
