Hi Trevor,
I was, of course, joking about mould inside the tube.
However the black marks are definateley not on the outside of the glass.
This morning i have adjusted the main power supply to the reccomeded voltage, this has perhaps slightly lightened the picture but it still looks dark. i.e. the black level is too dark. There is enough contrast and focus is so-so. Last night I cleaned the case and today I put it all back together again.
I cant do much else until I get a decent test signal into it. I have a colour bar program on my CP/M computer, I'll try that when I unpack it.
Kind regards, David.
