Is that a .1uF capacitor?  That would give about the right resonance
frequency with standard components.

I'll bet it would have worked a lot better for me than the 6299.  I
also noticed that we went through approximately this same discussion
10+ years ago, e.g., see:

http://groups.google.com/group/comp.home.automation/msg/7e7815cbb7cae2e8
http://groups.google.com/group/comp.home.automation/msg/e2ec87fedbbecadc

which suggest that either there was a different 6299 or else Phil Kingery
wasn't aware that it flipped the phase.  Oddly, in the Hometoys article
Dave referenced earlier in this thread, the simplified schematic of the
passive coupler appears intended to flip the phase but Phil still talks
about the problem of 240V devices as if it did not.
