Re: WG6100 tube swap

have you tried putting a tube rejuvenator on it?

the BK 490 i have, on top of the tube rejuvenation, does lots of snazzy
tests, including focus continuity, which i have had success on identifying
from your description...

i'm gonna be over in the US for cax, i'd love to try make the journey up to
say hi...
