Thanks for your help

Older ones have pcbs and if you aren't licensed to dispose of them its a huge fine...some have also been rewound with aluminum. If they have pcbs they are considered hazardous waste.

I have read that the PCB filled transformers are usually painted black or a very dark grey. The normal light grey ones you see should be filled with mineral oil.
They also say that right on the tag, NON PCB.
