I remember seeing something like it, it must have been about 40 years ago. I
don't think it was new, then.

Believe it or not, back when I was in High School,(80/s) these were being
sold by a surplus dealer for about $20.00 each, working. Everyone who was
into electronics bought one, including me. Mine has to be in a box buried
somewhere in the basement. They all worked really well.

Amazing! So who was the manufacturer?

That's astonishing. Wouldn't surprise me if it was late WW2 vintage.

I don't think so. It looks post-Korean War to me. You don't often see
terms like "Time base" and "Sync" (implying triggered sweep?) on WWII-
era gear.

I'll guess 1960. Vibrator supplies were still used then.

Hi John,

Synchronization was used in really old scopes. Or synchronisation as
they'd call that in Paul's country. Horizontal deflection oscillator was
usually the name for the time base and it was coupled to the input
signal for "locking" purposes. The amount of coupling could be adjusted,
too little and it wouldn't sync, too much and it would distort the
displayed waveform. I still have a trusty old Hameg from these days. It
has a sync knob.
