Telequipment D33R Oscilloscope.

My golly, that is old... Hope it still works. A scope is very useful if it does work.

I have at least 6 scopes of various sorts. Only use 2 on any regular basis, being a DSO 100MHz digital thing and a 20MHz 2ch Kenwood. Two are kaput, being the Tektronics 456 and a Hitachi 60MHz, then I have the tiny LCD kit toy that has its uses, and a single channel 5MHz antique that I picked up a a HemFest auction.

Of all of them the 100MHz DSO is the pick of the bunch. Once you know how to use it looking at any waveform is so simple. got it for AU$350 on ebay...

Apparently it could be either 1950's or 1960's vintage, so yeah it's an oldie, it's most likely 1960's vintage, I did manage to find circuit diagrams for the model D33, which is basically the same as the D33R which is in a 19 inch rackmount case, the seller said it was working the last time they powered it up, I'll need to buy some new scope probes soon.


I've got a more modern 20Mhz Dual Trace solid state Oscilloscope that I bought from Dick Smith Electronics with the help of my dad, back in 1998, it's still working, but I need to give the case a bit of a clean cause it's getting a bit grimey.

I'll probably need to buy a high voltage multimeter probe that can withstand up to 30kV if I ever need to do any servicing on the D33R Oscilloscope, oh and a good isolation transformer too.
