anybody know how to power an original 6-volt positive ground radio in a 12-volt neg ground system? thanks.

Yup! Randy Rundle at WWW.Fifth Avenue internet garage.com, Clay Center, Kansas. makes a resistor for just that purpose! 785-632-3450. By the way-The radio doesn't car about pos., or neg. One of my 1950 cars is 12 volt, and it works fine. Regards, Steve Lee

thanks steve, you're right, the radio doesn't begin to know the difference between positive and negative ground. with a mechanical vibrator anyway.

I understand electronic vibrators last longer but they may be sensitive to polarity.

Speaking of polarity, when I was in school back in the stone age, I used t run car radios off of AC (with the vibrator in it) by simply connecting it to a 12-volt transformer. Old car radios were a lot better than those sold for home use. Richard

The new solid state vibrators are polarity sensitive...

i checked randy rundle's web site and found a page explaining why a 12 to 6 volt voltage reducer CAN'T be used with an original radio. http://fifthaveinternetgarage.com/tech_tips_Why_cant_i_use_a_voltage_reducer.php nevertheless, I found one one that seems to work just fine. https://www.amazon.com/gp/product/B01CUA4KK8

You are talking apples and oranges. The Rundle voltage reducer is just a high wattage resister and the converter that you bought appears to be a solid state regulator, probably a zener diode that will not convert the voltage and current to heat. Tom

Yeah, but like I previously told you, One of my 1950 cars is converted to 12 volts and the radio doesn't seem to know the difference. Regards, Steve Lee

Who wants to listen to an old AM radio anyway. I don't! You can't get anything worth listening to; but if you must, send it out and get it converted to 12 volt AM/FM. Regards, Steve Lee

Uh, you say 12 to 6volt? I think you mean 6 to 12 volt. Regards, Steve Lee

sarahcecelia | -- 08-16-2017 @ 1:23 PM |
Your right, that's because it takes too many volts to operated the deal. Regards, Steve Lee

To listen to AM radio you have to be able to understand and speak Spanish very well!!! Regards, Steve Lee
