I think he meant the upper two cards in the pic (left of the WFC).
I also think that they probably really are part of the Steam resonator. But what happened to it? It really looks like it has been slaughtered (all the cable connections cut). So from the pic posted in the beginning of this thread there's not much informations anymore available of how this thing was interconnected.
Far more information one can get from the pic of the Home Heating Unit.
Here's the Steam-Resonator Driving Circuit of it:

I just shortly drew the interesting connections (as the Transistor's pre-driving circuit isn't really interesting).
So it looks like that:
The computer tells with 4 bits the amplitude of the primary voltage. This is done with the help of a LM317 and an additional Transistor.
Additionally the computer tells the Impulses and which side to drive.
The actual driving circuit is made of 2 PNP transistors (for driving the primaries), and 2 NPN transistors which make a connection to ground (with a diode in series).
So from this one can get the information, that neither of the two available schematic drawings of the Steam-Resonator is really what he used here. IMHO the lower transistors in the never schematic are only needed, if you wanna drive two different Steam resonators at the same time. But in the Home Heating Unit he powered all as one big unit (all tubes in parallel).
What's really interesting is the voltage rating of the transistors. They are only made to withstand 100 Volts. Also the Diodes used are only rated for 100 Volts.
Well for the primary driving circuit this is surely no problem. But the part which connects the Tubes to ground is problematic. Sure, if the transistor is on, all the voltage will drop over the resistor, and the transistor will be fine. But here's the problem: The other Transistor (on the other electrode) is not turned on during this time. This means it would have the full cell voltages on the transistor.
So my conclusion is: Either the Resonator only worked with very low voltages (< 100V) or the Electrode(s) were coated with some insulator.
Or any other ideas, which could yield an explanation for this?
Edit:
Another IMHO interesting detail: The Transistors are not mounted on a heat sink. This actually indicates, that besides the fact that this thing drives this huge Steam-Resonator, not much energy is needed.
@ HMS-776:
No the clean Tube you see in the WFC wasn't connected. The Steam resonator wasn't in there. It was in the water tank.
