Two toroidal transformers

I am selling two toroidal transformer cores that used to be variacs. The conductive tracks have been insulated with nail polish.
The larger core ($50) is rated at 240v 20A with a tap at 120v and the smaller one ($35) is rated 120v 15A. They can easily be wound with thick wire for a high current output.
The prices are negotiable.

Thanks,
Alex
