I have a question about checking resistance via chart in manual.

A tube check good on a tubetester, but the resistance is way off from the
chart. 5k ohms vs. 200k ohms. when the tube is pulled the pin measures about
175k. all other pins check within 20-25k ohms on every tubes including the
questionable tube.

does this mean this tube is bad or only unusable for this application. It's
the RF mixer in a Tempo one (the manual is packed, we had some floor
replaced and I can't get to it at the moment.

It's the first RF Mixer.

Thanks

Chuck
