Default JVC Headphones Voltage - Unknown WallWort

What VOLTAGE did this HA-w100RF JVC transmitter require??
***
I have a pair of wireless headphones. HA-W100RF. This is the model
with a base and vertical bar (antenna) that supports the headphones,
recharges the batteries in the headphones when they are not in use,
and sends the audio via RF about 150 feet to the headphones via 924
MHz fm modulated. Quite similar to the HA-W1000RF 900Mhz cordless,
but with a different stand.
It's basically a transmitter with audio input, and headphones with
volume controls. The set is complete except for the power supply
(wall wort). To repair these I would require the voltage for the
110V
black box (ac adapter). The transmitter is powered by this adapter,
the headphones use AA batteries.

If you have a pair of these could you reply to the newsgroup
with
the data printed on your JVC ac adaptor. The voltage and maybe even
the maximum milliamps.
There were not enough of these sold, and they are not available any
longer, for this data to be found in the newsgroups or on the web.
Even ebay sales are very low. Maybe one pair every season or so.
None, as of this week, and the past several weeks data is all ebay
gives access to.
One photo of a recent sale had the wall wort in the photo and i
couldn't get the voltage from the photo even after using software to
enlarge it, clean it up, and sharpen it.


Thanks, in advance, for your assistance, if you own, or used to own,
or repair, or have access to manuals for this model. Daveyjane.

Probably 6 or 9v 300-500ma. A polaritiy indication should be on the
device. You can also open the unit to look at it for a guess.

If your unit uses two "AA" batteries, it would make sense that your unit
required 3 Volts. You will have to open it up and trace the circuitry to
determine the correct polarity if it is not marked on the outside.

I would suggest starting with 3 Volts to try it. Then work your way up if it
does not work. You can do this with a universal power adaptor that has a
voltage switch on it.

As far as current is concerned, the device will pull what it required. Get
a universal adaptor that can supply a lot of current to be safe. There are
some models that are over 500 ma.
