Hi & thanks for reading,
I bid for this faulty 100MHz dual beam scope at a club junk sale & won it
for only 1.50. It had no handbook so I had to fault the "no display" problem
blind. I found a short circuit 22V zener in the complex brillance circuit, & I
also replace the EHT shroud that was missing, obviosuly someone had been there
& gave up on it.

Well it now works quite well, but I think there is another fault in the dual
timebase mode control, as there seems to be no difference between A timbase &
A intensified with B timebase, there is a very slight difference one brilliance
that is it.
Any information on this old piece of testgear would be very welcome.
