Hmm, I've thought about this a bit.  I think one could make 
up replacement SLT modules with little PC boards and SOT23 
transistors and 0805 or 0603 SMT resistors.  SLT modules had 
very little on them, something like 2 transistors and 4 
diodes and some resistors.

I was thinking about this in relation to keeping a mid-size 
360 running for a few hours a month at a museum, like the 
1401 at CHM. But, it would sure work for actual full-time 
operation, too.
