Not sure where I can pick one up in Australia. Any place selling it online and shipping internationally?

If you can't find an adapter, you could just buy an inexpensive 3-conductor extension cord at the hardware store and simply cut off the ground prong from the male end.

I had a pair of F112s and no matter what I did (including ground elimination, channel swapping, cable swapping, mains phase swapping, PC swapping, pre-amp swapping, etc) I could never completely eliminate noise (mostly hum in my case). I ended up selling them and buying my current ML Depth i subs - zero noise - nada.

Good luck

Had to have been something in my system though (or maybe I'm just over-sensitive to noise) - because both the guys who bought them LOVED them.

Guys, I am pretty sure that the "isolation" switch at the back near the PC connection lifts the ground, so no "cheater" plug needed.

Doggiehowser...Yes, I am using standard 3 prong plugs here in Australia. The isolation switch is at the default shipping setting of "isolated" not grounded. Currently they are on a separate shared circuit to the rest of the equipment. Zero issues here.

Separate circuits would be the best. This is something, I am working on too.

I would give that extension chord a go to eliminate possible grounding loop and/or issue with your power conditioner.

Sigh. The gear is in Brisbane now and I am stationed in Sydney for a while. Will only be back at the end of the month to muck about.

I am in two minds to take the PurePower out but the power supply in my suburb trips quite frequently and I am not convinced I want to risk some of my gear hooking them directly without the PP in the chain.

In fact, if the blue tab touches the outlet plate retaining screw, you will still have the ground. The best thing is to break off the tab.

These are about 69 cents in a big box hardware store like H-D. (I don't know if we can say that name)

It's going to be a failure in the subs electonics. I'm so sorry it happened. Over the years I have wrestled with leaving my equipment on during the night time hours when asleep. I finally decided to turn the equipment off at night. Then the next day I turn it on and leave it on till I go to bed, as a general rule but I will always turn it off before sleep. One might think this a silly rule but it has worked well for me over the years. Probably wouldn't have helped here though because you have a defective part, and this is not about prolonging the useful life of good parts.
