Re: PW Jan 1983 50 Ohm Dummy load
I built something similar based on a design by the American guy (Ken ??) who passed away last year who had run a business for many years servicing Kenwood (Trio) Hybrid gear. He had used Liquid Paraffin (the sort of stuff you give to horses and other animals to help avoid digestive blockages) complete filled the can, and had had it in service for a long time (100W to 30MHz).
Probably cheaper that Aeroshell by some margin!
