a real challange?

R1, R2 are paralleled by the tuner switch and those are in series with R4, R11. It's possible your meter is charging some cap, but I'm not seeing it at first glance. 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.

I'm not sure if its a tuner issue still or not, there is still snow in the pic, the 150 ohm resistors DO seem to be a bit off, but i don't know how much it is affecting anything in there.

I could try re-checking the plate resistance with a non digital meter, I think i have one, not sure.
the tubes in the tuner ARE new.

could this all be IF? or both, perhaps no way to tell really :/
