[R-390] Filter caps

[Cecil Acuff]

The octal socket idea is not bad and even under the chassis but always 
remember if you do the under the chassis replacement,  do not plug in the 
originals if you have used the socket bases for your connection point for 
the under the chassis caps.  You will make it look original but will also 
throw the leakage of the old caps in the circuit with the replacements.

On removing the old caps it takes more heat than hot water.  I had to resort 
to the propane torch to get enough heat.  I did find that the cans can be 
cleaned out with lacquer thinner once the majority of the black goo is 
removed.

The last ones I rebuilt I didn't reattach the cans.  I just floated them 
over the rebuilt bases with the brackets holding them in place.  Makes 
re-entry a snap.
