Hi Fred & all....

you must have been missing the one tool which made it easy ,,,, my good ole
Hakko solder sucker, which i bought before swapping all the crystals in the
K2 crystal filter.

 

Bill I have numerous suckers including a thousand dollar desoldering
machine. The problem is suckers tend to generate solder balls. Like the
other gentleman that replied I used solder wick. I also took considerable
time to clean flux residues, ohmmeter the circuit, and inspect.  Yes the
documentation is excellent and no it's still not a simple task, particularly
if you have poor eyes, arthritis, or drink a lot of coffee which are the
questions I heard Dennis asking.

I opened up the bottom , top & back Fan assembly.

>From the bottom, with the set upside down, let the Hakko do it magic on the
four pads, which dropped the two parts on the table....  then inserted the
two new parts,,,resoldered,, lids closed.
