The "oil filter" housing lead is the one I referenced in this thread. There are also two other electrical connections at the base. One appears to feed the "cathode" grid and the other seems to feed the center rod, what I am calling the "anode": http://jlnlabs.imars.com/mahg/diagram.htm Note in the ou tests, it appears there is no connection to the "oil filter".
