this may not be much help , but i have done this , i had tried a few reducers that got too hot for comfort , then one day at a swap meet i found a much larger ceramic body reducer that houses a coil inside it to burn off what your not using . i have it hooked up the 6Vradio and the 6V heater even a 6V spot light . and everything works just fine so far . its about a 4 inch white ceramic square about an inch thick i mounted under the dash . im no electrician and was very leary hooking it up to my working radio as i have read so many horror stories . i just went n stood on my head trying to look at it ,but it is difficult to see "American voltage drop " and it has two output connections depending on the amperage desired . ...OK i did a little searching and found what i have here _http://www.parts123.com/parts123/yb.dll?parta~dyndetail~Z5Z5Z50000014a~Z5Z5 Z5AAECD~P45.00~~~~S3N40U21OW71119123214x~Z5Z5Z5~Z5Z5Z50000014x_ (http://www.parts123.com/parts123/yb.dll?parta~dyndetail~Z5Z5Z50000014a~Z5Z5Z5AAECD~P45. 00~~~~S3N40U21OW71119123214x~Z5Z5Z5~Z5Z5Z50000014x) not sure if these links will work but "the filling station has em $45 dollars each ......steve 53 gmc In a message dated 11/11/2012 10:20:46 A.M.

If we are talking a 6V radio, then we are likely talking vintage radio with vacuum tubes. They drew tons of current. I think the best bet here is a dropping resistor. To figure the value of that resistor it is best to actually measure the current draw of the radio while it is hooked up to a 6V power source. I remember how quickly leaving the radio on could deplete the battery back in the day. Stop at the local tavern for a beer and leave the radio on, and you would come out and your car wouldn't start. Then you would have to go back into the tavern and drag 4 or 5 customers out to push start you. Jeez I hope I an not the only one here old enough to remember doing that kind of stuff all the time ;^) Tom [Non-text portions of this message have been removed] ------------------------------------ Ole Chevy and GMC trucks rule!
