Sony ICF-7600D Manuals

It should be possible to tell if it is 33 ohms orange-orange-black-xxx or ohms red-red-brown-xxx. I got the folding twist right virtually on the first try after use, the antenna has to be folded together again, which had been reported as being a bit tricky until you get the hang of itthough it’s quite possible that it would be more difficult with a stock antenna frame.

These free programs sony icf-7600d service manual be found on this page: Now consider two scenarios:.

Maybe later models were improved in this regard? The original circuit diagram shows R66 connected between the source of Q11 and sony icf-7600d service manual. Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies.

If spny need a service manual in paper form, there are various sources that sell ’em. You can also find a complete ICFD service manual online these days.

In off mode there is working a 3 V linear regulator. Oh boy, I certainly have come a long way in terms of headphones since I wrote the paragraph below.

All the rest is entirely discrete, with 13 transistors, 1 FET and a bunch of diodes. Proper gain distribution in battery operated receivers is not at sony icf-7600d service manual easy, as not only signal levels on the whip in particular may differ quite a bit between battery and mains operation, but also dropping battery voltage may lead to reduced gain.

You can write in English language into the forum not only in Hungarian! If anybody has further information, please let me know. sony icf-7600d service manual

What I would suggest to have done is:. Both of these are totally open, however. Bad design, simple repair but took some digging in the schematics to find out what exactly was going on! Fri Jun 10, 4: Sony icf-7600d service manual quote the Sony supplement: Five of the ten components which were changed were on the antenna board. Created yyyy-mm-dd Last revision Unfortunately, its availability has never been too great apparently it’s only being servuce once in a while, in small batchesand the price may also seem a bit deterring, given it sony icf-7600d service manual about half as much as an ICF-SWG R when new.

A black case was introduced. So, what about a little review? Then, because of a lip on the right lower side, I open the backside turning it like a page from left to right.

Via PM, Bernhard told me that he had, among other things, changed the frequency response of the audio amp because originally it was too muffled. I believe that this sony icf-7600d service manual covered the infamous warranty changes which Sony made to the ICF starting late in or early in sony icf-7600d service manual The bandwidth of the various stages also plays a role, as it not only affects sum signal levels but also decides on which signals can still generate unwanted intermodulation products in following stages.

The original model was issued in a silver case. I’ve retired the AN for now.

The Sony series page: ICFD/DS, ICFA, ICF

Unfold antenna module and attach it somewhere that’s a bit of an unsolved problem on this antenna, you can clip it somewhere and attach it to windows and such, but that’s about itconnect antenna controller to both antenna and receiver if you were wondering what the somewhat strange-looking longish part is, that’s a filter mnual which you plug in the cable from the antenna controller on one end and connect the thing to the antenna frame with the other sony icf-7600d service manualput siny two AA batteries into the antenna controller I used rechargeables, since I didn’t have anything else at hand, and these work pretty well, with the switchoff voltage being roughly 2.

If you need better reception “on the go”, the AN-LP1 makes a good travel companion. This is the way in which appears in the cct diagram in the supplement. A circuit simulation via LTspice had shown the following -6dB points:.
