Hi Siggi,Hey Denis thanks for the reply.
I hadn't realized that the collector supply would affect the intensity as
well, but I can see it now in the schematic. I'll have to look for that
when I dig in.
The brightness control should work regardless of how long the collectorRight, thanks.
BTW: Nothing like reading the manual - on page 2-3 of the service manual
Provides continuously variable flood-gun current duty cycle from about 10%
to 100% (when the collector sweep is turned down or disabled), permitting
extended retention of displayed information. Also controls the degree of
spot dimming when collector sweep is turned down or disabled.
And on the schematics I see that the intensity modulation and the flood gun
current duty cycle are indeed tied together. It all makes sense now.
