Question: I want to buy this. One review states that it doesn't come with an AC adaptor.Which adaptor do I buy -prefer one shipped from Amazon
Document: But, afterall it is shortwave radio quality. I haven't listened shortwave radio for years, and cannot make too much judgement on that. (3) It doesn't come with power adaptor.But, if one want to buy a GOOD shorterwave radio, there are not too many options.
Verify... verify... I had placed the Sony ICF-SW7600GR (currently in the $150 range) into my shopping cart after reading the positive reviews and yet one attracted my attention at the last moment. Within that review, the author mentioned that the AC power cord was not included.Amazon reported the power cord was no longer offered (Sony ACE60HG AC Adaptor $22.99); so I searched about the web to discover the AC power cord is $49.
Standard AMreception is good, possibly very good. But if you areinterested in DXing the AM bands, you already have aGE Super Radio.It doesn't have an AC adaptor (and you should AVOID buyingthe horrible--and horribly expensive--official Sony adaptor).If you want to power from AC, get an inexpensive one. I powermine with rechargeable NiMH batteries which work better thanalkalines and can be reused hundreds of times. Buy twosets of batteries and you'll always have a set charged andready to go.
The radio does not come with an AC adapter, and the original Sony meant for this radio is hard to find. Luckily I was able to snag one on Amazon. It is very quiet, and I have heard some of the aftermarket adapters are noisy.2. Sound quality is pretty bad. I may have just been spoiled by the excellent speaker on the CCRane, but this radio's speaker is not up to snuff.
The radio certainly has plenty of features which should make for a good SWL radio. The first issue was the difficulty of tuning without a manual knob. And good luck decyphering the instructions on using the various menu options and memory features. They do not make this an easy radio to use.The other problem is the radio did not come with an AC adapter. I ordered one from Amazon which was advertized to work with this radio and it does not fit into the jack.
This radio was perfect in every way with one exception. When I plug in the appropriate AC/DC transformer, the volume stays "low" until I push the "backlight" button for the display, then it jumps up to a much higher volume. I did not want to bother with returning it, since it works great otherwise.P.SFor the record, do NOT buy the transformer "recommended" as a complimentary item to purchase. It is the wrong voltage.
This is my first negative review on Amazon. The Sony ICF-SW7600GR I purchased from Amazon is a huge disappointment. I could not believe how bad the FM reception is. Only a few stations come in clear, others have interference from nearby stations, or can only be heard if the radio and antenna are held in a specific direction. My Radio Shack clock radio, Tivoli Audio, and any car radio have better reception!
Just a quick review. This product is great for its size and cost. The options for fine tuning really help finding and keeping the stations. My only complaint so far is that the product did not come with the AC adapter so I had to purchase separately. Seems a bit strange to not include the AC plug.The unit feels solid and well built. The instructions/buttons are a bit complex but maybe that is the norm with SW.
;-)  Come on, Sony - at that price, a cheap 6v plug-in power supply ought to be included.Second, and this is a BIG hit on Amazon - DO NOT buy the Sangean antenna listed as "frequently bought together" with this receiver. I got caught on that and purchased something that is IN THE BOX.
I have noted a number of reviews mentioning that the Sony ICF-SW7600GR, in my opinion the finest small portable short wave receiver available at the present time, does not come with an AC adapter.I own three (3) of these receivers (as well as two of its predecessor receiver the ICF-SW7600G).Believe me, you do not need (or even want) an AC adapter.
Answer: The Sony 6 volt AC power adaptor AC-E60HG is a recommended unit for the radio.  It is large in size, but well filtered and produces less radio hum.  Radio shack had a 6 volt AC adapter CAT. NO. 273-1761 that works with the radio, and they allow you to select the special sized plug that fits the Radio.  However, the Radio Shack adaptor is not as well filtered as the Sony adaptor and it generates noticable radio hum.
