John -

Thank you for your interest in my books. I do not plan on upgrading any of
the books I wrote in the past. I did start on a book for Tesla coil testing
but work has sort of stopped. I am 85 so I do not make much progress in
anything I do. Tesla coils still hold a lot of unknowns for us to search
out. At present I am researching the proper TC inputs for optimum conditions
especially power factor and spark length per joule. Power factor under
instantaneous and current surge conditions is a complex subject.

Hello,

Does someone have a rule of thumb for determining  primary outer diameter
based on secondary diameter and height?
I did an archives search, but came up with nothing definitive.  I am sure
that there is a ratio for optimum performance.  Also, if John Couture is
reading this, are you planning on publishing an updated version of your
construction guide?  Mine is from the early 90's, and I was curious if you
are planning to integrate some of the last decade's developments into a new
book.  I certainly hope so.

Thanks,
John Richardson
