Ron,

Leaving rosin flux on solder joints is a sure sign of amateur
workmanship. If it came from either a repair shop, or the factory, it is
inexcusably sloppy work, and may go a long way to explaining the often
related poor reliability of English electrical systems. It is the
electrical equivalent of assembling an engine using a lubricant with
dirt in it.

Sorry to hear your plight. I do believe there are flux solvents that can
remove these contaminants without physically disturbing the circuits or
mechanicals.

Another "solution" would be the resoldering of the connections with a
low wattage electronics design iron (not a pistol grip). This might even
be better, as I will wager that if the flux wasn't removed the joint is
probably "cold-soldered" as well. This is another no-no, and another
cause for measurement errors or just plain failure.

This was such a major flaw that I couldn't even find something humorous
to add.

Steve
