Clear audio professional or klaudio record cleaner

And you'll want to find out the kHz of the Ultrasonics from the manufacturer. Makes a big difference according to threads on DIY Audio.

I too am interested in buying one. I am not counting on a step-up transformer
though. It would be nice if it works but I'm OK with it running off my dryer or
hot water circuit. I suggest a back-up plan if the transformer doesn't work out.
A google search of the suitability of those transformers suggests they may not
work in many applications. You can't just boost the voltage, there needs to be
120V applied to each leg of the circuit for many appliances to run properly.

"You can't just boost the voltage, there needs to be
120V applied to each leg of the circuit for many appliances to run properly."

Above statement is not correct and I'd strongly encourage you to use a step up transformer, and not connect the unit to your household 220V two phase circuit.

The units, if made to be operated Europe and Asia which have 220 to 240V AC voltage relative to Neutral. If made to operate in the Americas where the nominal household voltage is 110-120V relative to Neutral they will have a different mains power input circuitry (transformer or similar).

This device is vastly different form a Water Heater, AC unit or an Electrical dryer for examples which are designed to run on two phase 220V, the Record Cleaners are not, and again, I'd strongly encourage you to use a step-up transformer should you decide to order one up.

Im sure Jim (Jea48) will chime in on this one if he sees this tread

200W Step up transformer

Above link to a suitable step up transformer, I assume that 200W is enough, I tried to look for the power consumption of the Amari RW800 but could to find any info on it.

If yo go with the RW600, the AudioDesk knock off, it operates on universal voltage, 100V to 240V so no additional hardware is needed for this one.

I'll update with information when mine, RW800, arrives next week some time.

Good Listening

Great. I'm excited to hear how the unit works.

I'm going to purchase the RW 600 I will keep you informed about it's performance. It sells for about $1400 on E bay.
