[R-390] Power Supply Module caps

[chacuff]

I did that on my last rebuild with the exception of taking the ground back 
through a tube socket pin to below chassis.  I cut the bottoms of the cans 
off...cleaned out the gook, sliped the cans over the caps and reattached 
them to the standoffs.  The cans were hovering over the caps and all 
appearances were that things were original but it allowed the caps to be 
replaced in the future if needed.  I thought came out quite cool and will 
probably do it again.
