Typically, items that are approaching, or exceeding       30 years old will have some marginal parts within. Further, if those parts are       'common' as in "many        of them", if one fails the others will not be far behind. Some truisms:              a) As in the Holland America commercials - Time is a precious commodity.       b) Most (not all) hobbyists are not limited by cost constraints for a few       parts. So, a US$20-or-equivalent investment to save a valuable item is not       outrageous.        c) Most of the effort in repairs is 'getting to it' - the taking-apart, the       testing, documenting, and then reassembly.       d) The actual repairs take very little time.               So, when whatever the device might be, when it is taken apart, *THEN* is the       time to refurbish the entirety to the greatest extent possible - to avoid       having to repeat the process if nothing else. Analogy: the engine in your       vehicle spins one (1) bearing.        You would replace _ALL_ of the bearings, as the incremental cost of the       additional bearings against the cost of the tear-down is tiny, and the rewards       significant. There is a school of thought that suggests that repairs are made       only to the minimum        necessary. Subscribers to this theory are the ones that one sees stranded on       the side of the road in a blinding snowstorm.               Your power-supply went through a traumatic event - and it is supplying a       complex and expensive piece of equipment. Consider it in that light.               As to soldering and technique - time and repetition will give you more       confidence.               Peter Wieck       Melrose Park, PA               --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
