[Johnson] Resistance Measurement

I would like to ask a favor of some one out there who owns an Invader 200 or
2000.
I need a measurement of the resistance to ground at pin 2 of V3, the 6CX8
heterodyne crystal oscillator and mixer. I believe there is an error in the
resistance chart but I need another measurement to confirm this.
You can make the measurement without removing the chassis from the cabinet.
If you don't have a tube extender, just wrap a short piece of wire around
the tube pin and put the tube back in the socket. The manual says that the
resistance should be 10K ohm. Mine reads 100 ohm. I'd like to know what
some one else gets for a reading.
Thanks,
