I've just looked up the RadioMuseum page, and that Manual, Mark, and was also concerned about that spec. being quoted as <10M in parallel with >50pf. As you say a bit vague. I do have the printed operation Manual somewhere, but it no doubt states the same as the on-line one! My M3800 is the Chinese made one, not the S. Korean Metex original. I still have a Fluke 75, but the rotary switch, or more correctly, the 'click stop' facility in that failed. As to the cellar, yes it does get damp, and, because of that, I've had to repair my AM/FM signal generator twice, when it had never given any trouble before. I'll try another valve in the R/Player, and check the cartridge's o/p with the M3800, then, if neccesary, take it from there. (and this was going to be a nice simple job!!!)
