I intend to have two dummy loads in the same "can" with each consisting of four 8 ohm 20W wirewound resistors (Radio Shack specials) connected in parallel making it two 2 ohm 80W loads. Each load has its own binding posts so connecting in series gives me 4 ohms and in parallel gives me 1 ohm allowing for 1, 2 and 4 ohm selections. Maximum dissipation is expected to reach around 1KW for short durations. Duration can be such that using the resistors as is, without the oil, is not an option.

It's practically 100% mineral oil. I built the DL Saturday gone. Works fine, gets hot but no smell. Got the mineral oil at a CVS pharmacy (USA) around the corner, something like $8.00 for a quart.
