Hi,

The advice to clean those sockets is good advice. I did clean dust and 
grime off all the sockets as well as off the bottoms of the tubes next 
to the pins. I tried a blast of compressed air but I ended up physically 
wiping the crud off and doing the 'final rinse' with air. artist brushes 
and tooth brushes were involved. Nobody washes their supper dishes any 
cleaner <grin>. The sockets look brand new even if some other parts of 
the old war horse don't.

73,
