That's very kind of you. I really must get my scope out and find out how to use
it. I think a good service would be a start. It's a Philips PM3214. Where would
I get that serviced and recalibrated?


Andy - switch it on, provided it works, you can calibrate it yourself.
It should have a calibration signal that will let you set the gain of
the vertical amplifiers, and adjust the trimmer capacitors in any x10
probes (tweak for nicest square wave).

As for frequency calibration, it is unlikely to be off, and it really
doesn't matter if it is a bit out - you aren't likely to be using it
to measure frequencies.

As for using it - just poke around and see what you see, get used to
setting the timebase to see clear waveforms, and the trigger controls
to keep them steady. And be careful only to clip the ground lead on
the probe to ground points in the circuit.
