Hi Bill  ya got me there ... no idea if it is that sensitive

i tried my luck with rolled caps   it was expensive time consuming and
frustrating when it arced thru 

then i went to plate caps    it was expensive time consuming and
frustrating when it arced thru   altho easier to fix  just replace the
arced plates

then i went to commercial caps  it was expensive  took 4 days to get
them and havent arc thru yet  

imagine  i could have had 3 sets of commercial caps   :(  

ahhhhhhhh  but i had the experience of building them   ;)
