Default Re: Oh no - another V4!

To quote Roy Walker: "It's good! But it's not quite right!"

Wiring the LOPT back up was a good hour's worth of finger burning fun - switched on and after a bit of twiddling got an .....almost full width picture!

EHT is up a bit at just over 10kV (my AVO8 seems to have lost its magnetism so this is an estimate) had to reset all the centring magnets and the frame amplitude and linearity.

Focus is a tad sharper and doesn't need to be all the way over. But width is still quite low. I've got to go out now but will try and get measurements from the line drive area again. I really can't think what it will be now other than a problem with the scan coils...

Cheers
