|
|
Hello,
My ampro started to act up, at first the brightness on the red tube started to vary until the whole tube started to go dim.
The tube does show a picture but not enough to project this on a screen.
As a test i tried swapping neckboards and the problem moved to the green tube.
Does anyone know this problem, or were to start looking?
Thanks in advance,
Lucas

If you shifted neck cards (RGB Output AMPS) and the problem went with it then that neck card is probably the root cause of the issue.

Exactly! I should still have a couple of spares if you need one.
