In 2005 I retubed my ARC VT-100 mk3. It has been used very sporadically over those years. The tubes are probably still good but to avoid issues I have now bought new output tubes. Back at that time a member provided great detailed instructions on how to proceed. Well I searched high and low in my papers and can't find them. What bothers me is that the one page instruction sheet from ARC that I have now found online is much shorter than what was provided through AA. The one thing that is so different is that I seem to remember having to buy two multimeters according to the more detailed instructions. Well maybe I had just misplaced one and then bought another, who knows, but I do have two meters in the box! My question then is: is there a procedure to do this job that uses two multimeters and, if so, why? I would also appreciate it if anyone out there having detailed instructions to make this chore as safe as possible would provide me a copy. I do have the safety test lead extension cables and also the ones with a plunger type thing to attach to the test resistors and will order a non-conductive driver for the trim pots since I can't locate the one I had bought previously. Thanks for the help. Pat
