Or maybe the meters voltage is setting up an oscillation, who knows. All those tuning coils should read relatively low DC resistance compared to the higher total resistance. Anyhow it appears you now have a decent B+ getting to those plates, so I'm getting a little lost with the ups and downs.

found 2 meters that worked well, my 16 year old fluke 77, says it's 4.39k so did the very old Micronta 22-220, but the no-name brands gave me crap, but the fluke did give the same reading as the crap ones did for the resistors on the grids. about 438 ohms.
