NO!

Having been a DIY tube electronics builder a long time ago, I even bought a 230 to 220V transformer back then, because all of the vintage tube stuff works on 220V. I think they are still available, but I don't know for sure.

You are right. 230V in Greece (at least that's what my UPS reports). Since you brought up the issues with older calculators, I have a nixie ELKA calculator that requires 220V. I have been running it on a transformer 110V->220V in the US, but have not plugged it in at 220V/230V. You think that 230V would be an issue? I do have a 240V->220V converter...
