Hello all,

Several months ago, I had a problem with a 40 year old HB amp for 160.  Just sitting there, it started making an arcing noise (sort of) and showed plate current jumping around.
Now, I'm finally looking into it.  I'm using a HB hi-pot tester and am 
testing pieces and parts up to their voltage rating.  FYI, the plate 
voltage is 4 KV and most things are rated much higher. �I was checking 
things out at 5 to 6 KV with very minimal current showing.  Happy with 
that.
Question:  Someone once told me that new Eimac tubes were tested at 
twice their rated voltage.  Ok, fine.  What about capacitors?    
So, what should it test if it were brand new?
73 de Steve, NR4M
