Oscilloscope smoke so need a new one, any suggestions?

camerart · Dec 6, 2018

Hi,
My trusty (was) Oscilloscope has just given up the ghost, so I need a new one.

I'm used to 2x Channel. 10MHz, with delay, so anything better than this. A storage facility would be good too. If possible a 12v powered one would be handy sometimes, though not too important. Middle of the range.

Any suggestions please.

Hi I,
Are they on Ebay now? I just did a search, and I couldn't see them.

Smoke.
Sounds like the Ht winding on the transformer.

Or connecting common (i.e., EARTH) to someplace other than earth. You can't just measure across any part you want with (most) scopes.

Hi P,
May be, but I'm not going to open it. I don't like high voltage!

Hi J,
I notice on the power cable, a note saying 'No Ground'
Also a label, last calibrated 1991.

Hi I,
Just bought the one you pointed to, Tektronix TDS220 2 Channel £230. With a lead cable, and has had the recall.
Thanks C

Hi Dr,
I notice you edited a line out of your message but it appeared in my inbox. I'll think about it, thanks

Well spotted.
I removed that as I know you dont like high voltage & pulling the thing apart might give you a nasty jolt, as the tube can hold a charge.

Just stick the entire thing on Ebay and sell it as for spares only.

Hi DR,
I gave it good coat of looking at. Thought about all of those switches and reclaim bits, as we should really, then cut the lead off it, and put it in the scrap queue. (I've got enough reclaim bit in the shed already)

Hi N,
A possibility.

I repaired one that did the same thing.
But I dont think I'd do it again, rewinding a trans isnt a good spend of a day.

I need to start spending more time thinking about the spend before I head down rabbit holes.
