Old vacuum tube scopes "What Can Old Test Gear Teach Us About Electronics?"

[lordvader88]

I also just got 1 of these old 1960's RCA WO33A tube scopes. However mine's been dropped or thrown badly ? (I wonder if anyone was killed???) The board is broke right in half and the CRT has some ceramic inside broke off. Very nice clean layout, sure hope the CRT still works when I fix the rest of it.

However Mr. Carlson got 2 of these easy, and they work. Here's a good detailed video on them and in-depth on tubes circuits etc

Yeah, it was neat seeing inside those. Hope you get yours working, too.

Those little RCAs were rare as hen's teeth in Oz.
AWA had a tie up with RCA, so some of the AWA 'scopes may have been licence -built versions of their units but again, I only ever saw big ones with 5inch screens.

The old Perth Tech School had some Cossors with similar performance in their labs, & there were quite a few Heathkits around back in the late 1950s/early 1960s.
There were some Philips ones with similar specs, too.

They were really already Dinosaurs, as Telequipment had the "Serviscope" available in a similar sized package.
The Serviscope had 5MHz bandwidth, proper triggering, & coax inputs (albeit SO239s) in a similar sized package.
It was quite a bit more expensive,which if you only needed a 'scope for audio use probably put it out of consideration.
