Yes.  I suspect that my cap checker’s leakage test may not have been sensitive 
enough.  I have reinstalled the RF deck because I wanted to confirm it is indeed 
generally operable after all the work done, and it is.  Badly in need of a full 
alignment of course.  But there are a couple of things to take care of before a 
detailed voltage check through the full range of S402 on the V401 B+ circuit.
This might take a week or so to get back to.
Thanks for the coaching!
