Thanks Geordie.
There are slight striations on the left, these disappear with higher HT to the line stage, so I'll not touch the output stage till I have the CRM93.
So far then the set comprises an EF91 front end bar
30FL1 Video anp/cathode follower
30FL1 sync seperator/line oscillator.
PL36 line output
PY800 Efficiency Diode
PY33 HT rect
30PL1 Frame osc/output.
BRC950 LOPT
5uf heater dropper
And of course the flywheel mod and 7BP7 CRT.
