I have a USA ZX80 here in the UK, I've removed the diode to make it 50Hz and it works fine on a B&W camping CRT and I get the normal very dark picture on more modern LCD and plasm TVs.
The problem is, I can't get a ZX8-CCB working on it, I have four of them and they all work on another ZX80.
I've compered the video output on my scope (I'm not good at using oscilloscopes) and the ZX80 that works with the ZX8-CCBs puts out about 3V from the connection to the RF box, but the one I can't get working only puts out about 1V, so I assume that's my issue?
If so, how can I fix that?
BTW: I've tried adjusting the pots and haven't had any luck, but maybe one of them needs a major adjustment to make up for the low voltage?
Thanks for looking, I hope someone can help
