I think that RCA scope is all vacuum tube. If you need help troubleshooting it give me a shout.
It is, and it came from the factory with mostly film caps already. No paper and (almost) no wax, nothing to replace except for the high voltage capacitor (wax) and electrolytics. Thanks for your offer of help, i may very well take you up on that.
My plans for it are to turn it into a curve tracer, the procedure I just simply couldn't endure sacrificing my O-12 for. Always felt at home with vacuum tubes, it's when we get to the nineties era solid state that I get lost.
