Since you guys were talking about D VOM and A VOM meters, I just recently picked up this seco model HC8 cathode current meter. Its the best thing next to the scope! Basically, just remove the HO tube, plug in the appropriate socket, and plug the HO into it (its a socket in series with the tube) and you can measure cathode current right off the bat. No unsoldering leads etc etc. The meter gives current figures for all the different HO tubes. Very handy. It was given to me by my local service shop. I think all of use should have one of these!
