A few days ago ...
... there was a CRO on the bay that looked like I might get it cheaply. For parts only, smashed BNC, missing knob. Somehow it reminded me of the very first scopes I had seen as a young boy. And not much money lost, anyway. I actually got it for 6.50 € + 9.50 € shipping.
It is a Philips PM3230, a true dual beam scope:
The overall appearance of the instrument is (to me) that Philips tried to create an instrument for the professional market: The PCBs are layed out nicely, it is unclobbered, the trimmers are mostly separated from the PCBs, labeled and arranged neatly.
Alas, the ordeal of shipping - although not too shabby packaged - was too much for the power switch, and, even worse, for all those plastic PCB mounts. Upon opening, a small pile of broken plastic emerged.
Please note the huge diameter of the CRT where the deflection plates are connected!
There also has been a repair (attempt?) that does make me uneasy. Repaired/original channel side by side:
In it's current condition, I won't try to power it up (there are some broken wires from the not fastened PCB, after all). But at least it has got all tubes, so I won't complain.
From what I've read, the scope seems to be rather unstable. The combination of tubes and germanium transistors wasn't a match made in heaven.
One fine day, I hope I might see a trace on that screen.
One more thing: That was the time when they all used those 'quick open/close' screw-like mechanisms instead of real screws. If only they ever worked!
