Mineral oil is the usual fare. The Cantenna came without any,
and instructed you to go to the drugstore for a gallon of
mineral oil.

Transformer oil usually smells very "electrical", mineral oil
is mostly odorless.

I have an old Heathkit Cantenna dummy load. how can I tell what its

filled

with, Transformer oil (pcb's) or Mineral oil... sounds silly but it

just

started leaking and I have oil all over the work bench... I went to a

paint

store and got another gallon can and that took care of the leak. hi , but
it was about half empty.
