Re: Oscilloscope Collection / Junky
'Scopes - can't live without them!
First one I had was a single trace Heathkit, bought new circa 1970, and haven't been without one or more ever since......
including various Tek, Dynamco, Telequipment, HP, Solartron ones over the years. Also I built a Dual trace 'scope in the early '80's based on the 50MHz design published in Wireless World using a then expensive dual trace DG(?) something CRT.
At present, for daily use, doing mostly 'Professional Audio' testing:
Tek 465
Tek 468 (used only as 3 trace Analog)
Tek 7623A (Analog Variable Persistence)
Might seem more than usual for a single test bench, but to avoid earth problems when high currents or multiple signal paths are present, I use different 'scopes to look at inputs, outputs and other test points at the same time.
A portable for occasional 'site' work:
Advance OS1000A (20MHz)
Rarely used:
Telequipment D52
Telequipment S54A
and waiting patiently for some TLC, a second Tek 468
At present, waiting delivery of:
2 x Tek R7603 rackmount mainframes and a second Tek 7623A
Possibly qualifies me as a "scope junky" though!
Some are from Members on here, others from diverse sources over a number of years.......
I find for Audio that Analog 'scopes win every time over Digital ones when trying to see small spikes or other anomalies in waveforms and you just can't beat a good Analog 'scope (Tek 465) for seeing things like this in the attached digital image of the current and voltage waveforms of an Amplifier output
