For the short term is sounds like there will be a flood of transformers
around. However, for the long term it looks like we will have to develop
the means to defeat or alter the new transformers for our use. I would
love to get a scan, copy etc. of your x-rays if possible or get them posted
to the web. Also, if there is any manufacturer's literature on these new
designs, it would help to know as much about them as possible before one
takes the saws-all and cobalt drills to them. I would also imagine that
this has raised the cost of the transformer considerably... Perhaps the
transformer would still work even with all this fancy stuff? Perhaps they
would just make our coils a bit safer?
If anyone has info on these let's get it posted and let the fun begin!
I wonder if a Tesla cap discharged into the relay would help to weld it
closed :-)) Hopefully, we can figure out the work around before we ever
see the first one. Of course, the neon sign guys may do it for use if the
thing works as poorly as I suspect... Hopefully, the new gizmos will fail
often and send large numbers of almost new transformers to Tesla land... I
bet the new designs will be dropping like flies. Just a new bunch of parts
to fail. This may be a good thing for us.
Sounds like a new challenge indeed! Just what we like :-))
