Hi Ted,Â
I dried the wood in the oven before I used it so hopefully it will be Ok. It should only be a problem if the oil absorbs moisture which may allow it to leech out the salts you mention. I can't imagine that anything soluble in the oil itself would be particularly conductive.Â
I posted a few more coil pics yesterday. Â Unfortunately I only make time to write posts on the bus so I don't elaborate too much. Feel free to ask any specific questions.Â
I have some concerns about the MOTs holding up as I didn't remove the core connection. I think they will be fine in parallel but series might be a stretch.Â
Even in parallel I will still be charging the tank cap to over 11kV. This is a tad lower than what I want, but it will still give me a few kW with 0.056uF. Or, I can run my mmc trays in parallel for over 0.2uF. Just not sure if 8 caps in series would handle the current. Any thoughts anyone?
In fact, if the mmc held up I would probably rather go this way despite the high gap losses.

Hi Greg et al
Re the use of wood in the oil baths
I assume you put ALL MOT's in oil (even the one with ground connected inner
secondary) for heat removal as well as improved secondary to core
insulation.
I'd consider very carefully the use of wood in the containers as over time I
suspect it will degrade the performance of the insulating oil as impurities
in the wood leech into the oil. May be better to select an appropriate
plastic or other inactive insulating material. Good luck with phasing this
array up.
