[TenTec] Corsair II problem

[Dr. Gerald N. Johnson, electrical engineer]

Many times an intermittent responds to alternated heat and cold. You
need a source of heat, such as a hair dryer, and a source of cold such
as the product "Freeze mist". The canned cold is available at Radio
Shack. 

Generally applying heat accelerates the intermittent, then cooling cures
it. Do large sections of the radio at first, then when a region of
temperature sensitivity is found, bisect that region for the next
heat/cool cycle. Keep bisecting and you should get it down to the
component. Try soldering it back first before replacing it.

Small aluminum electrolytics the age of the Corsair II are highly
suspect. Some weren't much good when new and don't age well. If there's
one bad, it may be worth the bother of replacing the whole lot of them.
