Gary,

I've been getting in all the last minute radio control 3D model flying 
the weather here in the northeast would permit.

Low power may be a matter of perspective. :^)

It's been mentioned before on the list that I use powerline ground in my 
lab, but I do a lot of Tesla related things that many Teslaphiles don't 
agree with. Safety gaps wired directly to the terminals on my tank 
caps.....oooooooO. Never lost a cap yet, but saved many, because of the 
SGs. Don't use paralleling chokes on any of my Variacs or Powerstats 
including the six section Powerstat stack I use to increase the line 
voltage going into my control cabinet....ooooooO. Chokes just aren't 
necessary for short term Tesla use if you check to make sure the 
separate sections track within a volt or two of each other and make sure 
that the wipers are tight and won't slip on the shaft. I could go on, 
but won't.

The lab is separate from the house, but is on the same pole transformer 
and I've never suffered any electronic or electrical damage from using 
power line ground. The lab is now equipped with an AMR electric meter 
that transmits meter readings to a passing truck and that seems 
perfectly happy too. No complaints from the neighbors either, just 
requests to visit the lab and see the coils. BUT, keep in mind the fact 
that my power cabinet and any other coil related equipment is connected 
to the line through VERY SUBSTANTIAL EMI filters. Even the ground is 
routed through the filters. To me, EMI filters are a must have.

Before the lab was built, I used the same filtering tecniques in the 
basement while producing 7 foot arcs and suffered no damages to anything 
electronic.

I am not recommending any of the above, just relating what works for me. 
YMMV!
