Hello,
my pm3267 scope vertical amplifier is broken.
I suspect the oq0020 and oq0049 ic's.
The manual doesn't show the internal function of these chips.
Philips has no info on them anymore, if you can help I would be very
grateful..
Greetings from Johan

The 0020 is a vert channel switch. and the 0049 is a vert amp-trigger
pickoff.
They are custem Philips chips.
