Re: Unpotted neon



Yes, without the shunts you will probably kill the secondary winding(s).  I
would recommend putting the shunts back and getting an additional
transformer to bring the power level up.  The nice thing about neons is that
they have the shunts.  This makes it virtually impossible to kill them
during use (aside from rf voltage break downs).  Used neons can be found
very inexpensivly at some neon sign shops.

To answer your main question, the big thing is if they draw more current,
they get hotter.  You can do some power heat tests by loading the secondary
and bring up the voltage on the primary slowly.  Then monitor the
temperature of the core.  Once you know what power level it takes to get
them hot, you can typically double that for short term operation of a TC
(starting from a cold core).
