Thus proving once again that there's an exception to every rule. It's
called the real world, gang. Budding engineers take note.

Every book on "how to solder" I ever read was correct in theory but wrong
in actual practice. You weren't encouraged to think for yourself but to
slavishly follow a set of rules that allowed for nothing.

Having a mentor is the best way to go (in any field of endeavor) if you're
lucky enough to find one. I didn't have any for many years and I was very
frustrated as a result.

>>> There's not one old-timer on this list who uses Ersin Multi-core?? For new
>>> construction the newer Kester's are the way to go but for repairing old
>>> equipment I'm still using Ersin. 60/40 at that. I have a lifetime supply.
>>
>> I used to use that all the time, but I haven't seen it in several years. Is
>> it still available?

Last time I looked it was, but that was a while back.
