Hi, I have a suggestion that I hope helps here.
Let me give you some theory to think with.
Alkaline batteries do not act like conventional batteries do. When they are starting to fail the initially
give you high voltage but the power goes down rapidly. In other words, the voltage spikes and dies.
If you have mixed different batteries which are worn un-uniformly, or mixed battery types. i.e. Alkaline with non-alkaline then you could have strange characteristic in your radio. In your radio, I would test with a fresh set of batteries.
If you have the AC power adapter for your radio, I would try that as well, to see if the same thing occurs.
If it is not the battery issue, then it is the circuit board inside the radio. The parts on these circuit board were designed to be inserted with machines and are often too small to be put in by conventional repair technicians. Sony will have the components to repair if necessary.
Let me know how this goes for you.
Hope I've helped
Best Regards,
Mark

My ICF-SW7600 has a clipping sound when first


It's hard to describe a sound in words, so I'm not sure I know what your "clipping sound" sounds like. You may be describing what's called "motorboating", which is a loud rapid putt-putting that drowns out the desired sound until it fades away. This is usually due to power supply problems, most often caused by bad filter capacitors. If I remember this model correctly, it doesn't have a built-in supply so you need to run it with an external adapter. That may be the source of your trouble. Try a different adapter or use battery power to see if the problem goes away.

If this problem only shows up when you're tuned to the station on 93.9, your radio may be picking up some kind of interference. It's also possible (but very unlikely) that the radio itself is producing a "birdie", which is a false signal on some frequency. If this is the case, it's a very obscure problem that may be very hard to find.

Sorry I can't be more precise, but maybe this will get you started. Thanks for using Fixya!

Advantage of (1980s and 1990s) Sony ICF-SW7600


Some newer radios do not have the quality build that the old ones had. The switch over to cheaper labor countries have lessened the quality and lack of good parts have lead to newer designs but not always better. My old SONY ICF-7600, not the G or GR, has a great receiver on LW and MW but after replacing aging capacitors!

Sony ICF SW7600 Restore PROBLEM


Sony radios of this era had notorious capacitor problems.... also several other brands were affected. These capacitors were underrated and the technology to make them was not at it's best back then. The cure is to replace the capacitors on the board with new electrolytics. About 28 of them need to be replaced but the big problem is to find someone to do this. the original capacitors are surface mount and must be removed and new radial lead caps put in their place, some are rather tough to get at and the new ones have to be placed carefully. My SONY ICF-SW7600 now works as new and maybe even better!
I have done this myself as I have skills working with surface mount capacitors. I offer my services to those who cannot find service for their radios. Please email me for details, I am not into making bucks on this, I just want to see these radios kept working and bringing enjoyment to their owners.
