Anyone know where I can get one? It has a special-sized socket that I am
having trouble matching, so I imagine Sony builds an adapter especially
designed for the radio. Amazon doesn't have it, so I'm not sure where to
look...

Any help is appreciated.

I find that those cheap ones that have all sorts of differnt size adapters
work fine, and only cost a few bucks
Van

Heh, Yeah, I've got one of those. Only it doesn't have a plug that fits.
Need to call up Universal Radio...

Thanks,

AC adapter for Sony ICF7600GR?

Do a search for:
Sony 147612111 ADAPTOR, AC (AC-E600)
*** $100 ***
120V/220V AC input
6V DC output

This is the original AC adapter for the 7600GR in Japan.
You will need an adapter for the AC plug which is available at Radio Shack.

Go to your neighborhood Radio Shack.

Be sure you know the voltage and amperes you need. Once the AC adaptor
is selected, the salesperson can choose from a large number of plug
sizes to fit your socket, and give you the appropos plug. (Take your
radio, so they can try the plug in the actual socket.)

Tried that, just to save time. They don't have a plug which fits the
7600GR, although they come close. That's when I decided to look for the
real thing...

There is absolutely no reason in the world to use a switching supply for
this.

The radio doesn't require much current, but the switching supply will
be far noisier than a linear supply unless it's really carefully filtered
and shielded.

Well, switching or linear, whatever. The point is, if the Sony AC
adaptor is so hard to find, and it's $100, a small, conventional power
supply would suffice.

A communications-quality switching supply would work (all ham
transceivers nowadays are paired up with such critters), or a standard
linear supply.

But the reason transceivers use switching supplies is because on
transmit a lot of power is needed.

That requirement isn't there for just a receiver.

But the "cost" of a switching supply in the application is the noise,
or the real cost of something carefully filtered and shielded, or
doing it yourself, to keep that noise to a minimum.

But that cost has no return, since the receiver requires so little
current that a linear supply will be small and not heavy, and
efficienty will not be an issue.

Dave,

For "Fixed" Location Radio Listening and Use consider building a
"D" Battery External Power Supply for your Sony ICF-SW7600GR
Radio. Buy the Four (4) "D" Battery Holder at RadioShack or
order-on-line. Get the right size DC Input Plug and wire the Holder
to the Plug. For Normal Everyday Radio Listening : A set of Four
(4) "D"Batteries should last about Six (6) Months or more in the
Sony ICF-SW7600GR Radio.
* Four (4) "D" Battery Holder
RadioShack Catalog # 270-396
http://www.radioshack.com/product/in...ductId=2062245
* 8-Pack D Enercell® Alkaline Batteries
RadioShack Catalog # 23-880
http://www.radioshack.com/product/in...ductId=2062187
Leave the Four (4) "AA" Batteries in the Sony ICF-SW7600GR
Radio -and- When the External "D" Battery Pack is plugged into
the Radio the Internal Batterys are Switched--Out-Off.

NOTE - The Sony ICF-SW7600GR Radio normally requires
6 VDC or Four (4) "AA" Batteries.

AC adapter for Sony ICF7600GR?

One problem with rectifiers is that they ground and unground the
RF path 120 times a second (60 Hz) and unless bypassed will add a hum
to a received station that has nothing to do with ripple. Many supplies
have this fault.

The effect is that the antenna system is changed 120 times a second.

I say go with batteries.

Having purchased NiMH cells and a charger, they're also useful for
other devices. Get 8 AA cells to start, 4 in the radio and 4 charging.

Don't let them run completely down. The clock in the 7600 will
run them to zero, and unfortunately the weakest cell gets
reverse-charged by the others if that happens, which is not good
for that cell.

Wrong theory on the hum but the right solution. I've giver the reason
for this a number of times and I'm not doing it again. Anyone that has
build linear and switching power supplies knows the reason.
