Re: B/W HV Diode Replacement Question?

John, based upon the Amplifone flyback section of that page, do I understand
correctly and an 19" amplifone tube can be replaced with a WG4600 tube,
without any type of modification. Mine has a small burned area in the
middle
and I'd love to put a non-burned tube in my Star Wars.
