Still clearing out my late-Father's electronics workshop. He was in the RAAF in WWII and trained as a wireless op/tech.

I came across this oscilloscope and would like to find out more about it. Does anyone have any information about it? To me it looks military but it doesn't have anything on it that identifies it.

It is a home-made piece from the late 1960s

Yeah, using one of those ex-military surplus tubes that every disposals store seemed to have boxes of back in the sixties. Radio, TV and Hobbies magazine used to publish designs for home built scopes like this. If you can find some copies of R,TV & H in a technical library or similar, you may even be able to locate the schematic and performance data this particular unit. I'd guess early to mid sixties would be your best chance. There may even be another forum member who has some editions of the mag, or the DVD archive of it that Silicon Chip released a few years ago, who could possibly skim through and see if it's in there for you. {:o)

If it's still in working order, it would probably not be useful for much more than audio work, although it may stretch up to a few Megahertz, and if so, could be used in valve radio servicing.

Don't expect too much from it though, as it's very old now and was probably not much of a performer even when new... Expect a blurred, sluggish and somewhat unstable trace at best {:o(

Thanks for the info. It's very likely that it came from an RT&H design as my father was a subscriber (he also subscribed to Wireless World and later, Electronics Australia). I've just put all the mags into storage - I'm not really sure what to do with them?
