Keith, WARNING kluge follows: Mount that TMC xfrmr on insulators, plug it in w. a series 250w bulb & see what happens. If it runs awhile OK, just use it that way. Ask the man who's been running a Johnston 500 that way for years. Plate xfrmr on 1/4" lucite. Forget about that de-potting lest we watch you on Judge Judy for starting a superfund site. Marty
