Re: the X-Ray transformer oil: RELAX! If it smells like motor oil and
floats on water, it's mineral oil. Dielectric Mineral oil is very often
a light straw color, that can darken with age and heat.
PCB-based transformer oil will not smell like chlorine - instead it will
have a sweetish, benzene-like odor, and the higher specific gravity of
PCB's means that they'll sink in water.
Enjoy your new acquisitions!
