Hi Steve,
Thanks for the response. I understand what you're telling me. What I need
to know is - when someone on the Tesla list says "use 3/8" tubing for the
primary", do they mean the industry standard 3/8" tube size (that has an
OD of 1/2"), or do they mean "use tubing that measures 3/8" OD" (which
would actually be industry standard 1/4" tubing).

copper tubing...)
;-)
Thanks for any info/assistance,
Tim
