Did everyone lose their Internet access?
Did everyone lose their power supply?
Power and internet must be back on by now.Comment

There was something up with the timebase, the 1-2-5-10 didn't work anymore.
Then it did.
Weird.
I never got to take the covers off.
I think I'll stick it back under the bench while it's still going.Comment

Your sillyscope is essentially an evolution from a sodding great valve. A hot element at the pointy end of inside a sealed glass funnel squirts electrons out which get focussed by some fixed magnets and some electromagnets toward the flat end of the funnel. The flat end has a phosphor coating on the inside which emits photons when hit by electrons. So the beam of electrons from the hot metal bit at the back appears as a dot on the phosphor.
A timing circuit applied to the horizontal-plane electromagnets applies a variable current to these magnets such that the electron beam is attracted toward one of the magnets and away from the other until it reaches a point corresponding to the end of the phosphor screen at which point the magnetic polarity is reversed forcing the beam back to the other side quickly.
Meanwhile an input voltage is taken from the thingie to be measured and that amplified by an amplifying thingie and that current applied to the vertical-plane electromagnets.
Some twiddly knobs let you adjust the base voltage and amplification of the input voltage so the up-and-downiness of the electron beam can be maintained on the phosphor screen by means of utilising a Mark I eyeball and some wetware to turn the knobs.
And it will have a power supply to heat the element and do the amplifying goodness.
So just sort out them bits and it is fixed. OK?
Anything else I can teach you, Zeity?My all-time favourite Dilbert cartoon, this is: BTW, a Dumpster is a brand of skip, I think.Comment

Well, aside from the CRT being electrostatically deflected, that was pretty accurate.
I had difficulty in understanding the timebase generator circuit.
There seemed to be a lot of bits & pieces in it.Comment
