Question about Personal Radios
I recently bought subject radio. it worked fine with batteries. it requires 3v adapter. iplugged in a 6 v adapter and now it is barely auidble. did i really screw it up?
I assumed this forum was talking about the kaito wrx911 since that was the heading but apparently that is not the case.
does anyone know what happens when a wrx911 is powered by a 6V ac adaptor? the input voltage is listed as 3V.

Upon further reading the kaito wrx911 manual i see where it says to change the batteries if the sound is low or distorted,so perhaps your radio was not damaged by the ac adaptor but is low on battery power. actually there is sometimes a voltage range that a radio can operate under. for instance,a radio may be labeled for 4 volt input but actually do fine with five volts.
and with ac adaptors there are always voltage spikes and surges. i was reading something about polarity problems with shortwave radio but im not sure if an ac adaptor would have anything to do with polarity shifts which can damage a radio. the literature i have been reading seems to suggest that using batteries to power the radio is safer than using an ac adaptor.
i attached a 6 volt ac adaptor to my kaito by accident. it was attached for less than one minute. the radio appears to be working as before. the manual says attaching the incorrect ac wire "could" damage the radio.
if you have to purchase a new radio perhaps you could still use your other one as a spare travel radio. the sound is barely audible but perhaps you could use headphones. doesnt sound like this low cost radio would be worth repairing.

From this point on six volt and three volt adaptors should be of different sizes to prevent this problem from happening in the first place and/or a radio like the wrx911 should have voltage protection.
you may have to purchase a new radio.

I also did screw up mine by overvolting it and it fried the FM receiver section. The TUNE light just stayed on and I couldn't hear anything despite the many strong radio stations in my area.

The ATS-909 is a 6 volt radio. It takes 4 1.5 volt batteries; that's 6 volts. Right? The adaptor for my ATS-909 radio is rated at 6 Volts DC. So if the adaptor you connected delivered 6 volts that should not have caused any damage. The center post of the connector should be negitive polarity (-). Your adaptor should indicate the polarity. If the center post of your adaptor is positive (+) that might be the problem.
Does the radio still work with batteries?

This radio can use 6 to 9 volts DC.3 volts would not power it fully. 6 volts DC will not hurt it.

According to the side of the radio, it uses 12 volts, not 3 volts for the adaptor with the center positive. It uses 4 c cells (6 volts). The reason its "too quiet" is that you don't have enough juice.

Yes you did! you overstressed the components of the radio plugging a 6V instead of a 3V adapter!
