Agree, and I'm sure you changed out the battery and cleaned the connections, cleaned all the switches and pots, tuvbae sockets, and replaced all the capacitors and made sure probe is OK. Yup, resistors are next, but they did sometimes use odd values. 1% replacements are now cheap enough even if you have to series/parallel a couple to be close enough. You can also get a couple of spare tubes pretty cheaply if you don't have 'em sitting around. So long as the meter movement is OK, not much else could be wrong --- but it may have been assembled by a kid who is now a grandfather like me.
