The tube is painfully bright! It's fitted with a Thorn New-Life tube which is handy. Though actually that's one of the faults I have to clear, it's so bright and neither the brightness or contrast control seems to have an effect! It seems C901 or C902 can be leaky or the beam limiter/preset brightness could be incorrectly adjusted, which wouldn't be surprising as I found a few things to be one ended for no reason, for some odd reason

Thanks
