That's worth a try. I'm waiting for them to approve me now.

As a side question, has anyone here ever removed the LCD color shutter
from the CRT? I have two similar scopes (a 544 and 744). The 544 has
a mint CRT, but there are some bad spots on the shutter. The 744 has
a lot of burn in, but a perfect shutter. I would like to swap the
good shutter onto the good CRT, but only if I can expect the results
to be good.
