Whatever, pretty reliable inexpensive frequency counters are available to check the accuracy of aging signal generators, which always benefit from a recap/recarb job and should be left on for at least a half hour to stabilize, and of course be very careful about grounding. I have changed a lot of such old test stuff to 3 prong plugs and know my bench is wired properly. I do use isolation transformers where appropriate, so it's been a while since I was last knocked on my **s.
