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,

era gear.
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.

Regards, Joerg

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.

I picked up my first scope from school. It was in 1971. Schools don't give away stuff unless it's really
ancient and they don't get given it unless it's really ancient either !

I'll guess mine must have been about 20 ? yrs old absolute minimum IMHO. Making it vintage 1950 ish ( pre-
Korean war ). It was a Telequipment. It was *far* more advanced than the one in the pic, although similarly
uncalibrated.

How old are Tek 545s btw ? I had a couple for a while.

Amazing! So who was the manufacturer?
