Electronic Visuals PAL Vector monitor EV4020 schematic/manual
 

Hi all,
Have an obscure intermittent fault on this vectorscope where the trace
flashes until brightness control is way too high (& likely to finish
the tube if I don't do something about it soon). Anyone know where I
might obtain a schematic or manual for it? (None of the usual sources
seem to stock anything made by Electronic Visuals & emails to a dozen
or so suppliers have drawn a blank.) Anyone help, pse?
