Hi,

Here is a link to a site that will give you information on how to dissemble
the radio.http://www.tesp.com/sw100faq.htm#fixed

I once fitted new ribbon cables to mine and found it to be quite tricky
and required a large illuminated magnifying glass and very steady hands!

As regards the removal of corrosion, I have never found a cure for it's
removal on other pieces of electronic equipment.

Good luck,

Once the corrosion has begun, there's no way to reverse the damage,
only stop the corrosive action. Various recommendations suggest using a
thick backing soda paste followed by vigorous and careful rinsing.

I've used this method with mixed results.

The biggest issue, once the corrosion has begun, is that the hard
plate is removed from the base metal, so oxidation is likely to occur
once corrosion has stopped and the metal cleaned.

There, I can help.

Once the corrosive material has been removed and the corrosion
process stopped, contacts can be cleaned with a dremel tool and
polishing rouge. This removes the rough and oxidation prone corroded
metal product, and rough base metal, returning the metal to a smooth
contact surface.

Coating the metal, then, with a neutral grease will slow further
oxidation. You may then have to clean the contact from time to time, but
serviceability will remain assured for as long as you own the radio.

Easy does it on the grease. "Just enough" is good. Too much will be
messy. And magically, appear only on your best or favorite white shirts.

You don't wear a white shirt to a barbecue joint for the same reason.

Natural greases with high pressure additives are not recommended.
First of all, they smell. Second, without a lot of high temp activity,
they will trap moisture, and will create more problems down the road.
Synthetic greases are good. Teflon greases are iffy, since some carriers
are water soluble and lead to some real nasty corrosion of their own.
Especially on zinc and aluminum. Petroleum Jelly works, if you check
frequently and clean regularly

Treating the contact, after cleaning but before applying the grease,
with DeOxit wouldn't hurt.

If you take your time, be thorough, you need not have any further
problem with your radio. It won't be 'maintenance free' but it won't
give you any problems, either.
