I was given a scope a few years ago, a tube based one from the 60s or 70s (actually it might be a hybrid of solid state and tubes) but I didn't really have a use for it. In the last couple of years I've started to get into electronics, but I COULDN'T FIND the scope!! Today I found it, it was hidden in our garage. I'd had nightmares about the scope before and what condition it would be in when I found it. The case was a bit rusty, so I cleaned it off and plugged it in. No pop or bang, but no traces. I fiddled with some of the knobs and the traces sprang into view, and the scope seems to work perfectly now it's all warmed up! After letting it warm up, I got my CD walkman with jack to phono leads on its line-out and pushed it into the inputs and it worked! :D Both traces were perfectly matched with the same gain and everything. I'm not sure what the bandwidth of the scope is, I don't think it'll go particularly high, but it's a fantastic gift! A oscilloscope is so useful in electronics.
This post doesn't really have a point, I'm just really happy to finally have a scope :cool: |

Congratulations. A scope is indispensible, even if just an old one with limited bandwith. Happy to hear it works too after all those years.
No problems with corrosion on the switches? That's a common problem after long term storage, but sometimes go away by exercising the controls a bit. |

Good going. Yes an o-scope is one of the most useful fundamental instruments next to a multimeter.
As for excitement seeing an old piece of gear come to life I know it well. You should have seen me last summer when a very early color televison from 1957 finally made it all the way from New Jersey to my home in Ontario and after a soft start conditioning with a variac and discovering a gassy HV rectifier tube which was easily replaced it mnade a perfectly converged color picture and clear sound. I was jumping up and down like a little kid with a new toy. :D
The fanfare was short lived for as I watched it the picture shrank, dimmed and finally disappeared as some of the critically placed ancient wax paper capacitors failed from absorbed moisture. Not unexpected really. I will be confident now to replace the caps knowing that the RF circuitry was all perfectly alighned and the vintage and rare 21CYP22 color picture tube is like brand new. |

| and hours and hours of wax gunk on your fingers from the old caps. |
