I think I bought Squibb's mineral oil but this was 25 years ago. It's
generic. Mineral oil is mineral oil, and it will dissipate heat. No, it
will not take 1,500 watts key down for a half hour but will your
amplifier permit you to do that?
Dummy loads are useful for tuning amps or a tube transmitters. Many people
don't use them and tune up on dxpeditions' transmitting frequencies, 14230
or 14247. Common sense and the FCC prefer dummy loads.
