The times it did not, we found other damage in other areas. Hard to find,
but if you use a little BLACK LIGHT you should be able to find all the acid.
Cleaning it can be a very hard problem.

Steve,
I would recommend that you NOT use the Tantalum caps. They have a very nasty
habit of shorting when they overheat in the summer. When this happens
depending on where the cap is, you may cause a fire in the radio.
Not a pretty when this happens.

Taking this into account you probable have close to 2.5dB loss through the
