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. TNX Dave 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, Dave |

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. "Dave" wrote in message ... "Bob Miller" wrote in message ...

Any help is appreciated. TNX Dave 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.) Bob k5qwg 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... Dave |

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. Michael 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. Michael |

TNX Dave 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.

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. -- Ron Hardin On the internet, nobody knows you're a jerk. |

Many supplies have this fault. Snip 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. -- Telamon Ventura, California |
