Nick,

Yes, but it fails when it cools again - something is not making good 
contact, and it may be residue from the cleaner.  I can't be certain of 
that, but I would get that cleaner residue off and try again.

I would suggest that you remove the cleaner residue from the contacts 
with acetone - apply it with a brush or cotton swab and immediately wipe 
the area with a clean cloth of paper towel.  Do only a few pins at a 
time, and do not let the acetone dry on the contacts or board.
You may want to mate and unmate the front panel and RF board several 
times, cleaning between each to hopefully clean some of the 'goop' out 
of the female header.

If you do not have gold pins on the connector to the front panel, 
consider asking Elecraft for the gold replacement pins.

73,
Don W3FPR
