What goes where on a Apex 460 tubesocket

[Greenie]

Hi.  I was wondering if anyone knows how the socketconnection for the tube on an 460 Apex would look like.  I don't seem to get any voltage into it, at least it doesn't light up.  I have enclosed a pic of the current state.  The mod is done on this: http://www.mark-o-matic.com/media/apex460-c12-mod.jpg-

Any suggsetioins?

The tube does not make voltage, only take and modify the voltage you send to it. So if you are not getting any voltage, follow back to the power supply.

Heater pin-numbers are *wrong* -- shows 12V across pins 4 and 9, which is a 6V heater segment.

12V on a 6V heater... it sure should LIGHT UP for an hour or so.

Fix that. Consult 6072 datasheet.

With correct heating:

Tube out:

Plate- almost 200V
Grid - zero
Cathode - zero

Tube in:

Plate- 90V
Grid - zero
Cathode - 1.8V

Hi and thanks for answering. 
Do you see any obvoius mistakes on the pic?

Thanks again PRR.  I did what you said and I found the problem.
