It appears the pump on my Audio Deske vinyl cleaner has failed. Cost for a replacement is $1380! It happens often enough it seems and the unit has to be sent to Germany for repairs at the insistence of Audio Deske Systems. A quick search on the net has revealed similar problems with some other owners. i know many will have had no issues at all, but for those that are in the market for an ultrasonic cleaning machine, I suggest they research the reliability of the machines and repair policies. before making a decision. A quick look at the unit shows that it is made of a plastic material that is plastic-welded all around. So the only way to access the pump is to cut through the joints and re-weld afterwards. This unit was not designed to be serviceable it seems .

I bought this machine while my Audio Deske RCM was still operational. What interested me was that it looked like it had been built by people who really understand vinyl and the record cleaning process. It is built by the Chinese company Amari which turns out to be a company with substantial engineering capabilities. They make a range of turntables ( sold under the brands Hanss Acoustics and Amari) , a number of different record cleaning machines ( including an Audiodeske clone ) and they also do OEM production and engineering work for other audio companies. The RW-800 is not fully automatic but it is the fastest record cleaning system I have come across. Along with other machines that can dial in ultrasonic power and cleaning duration, it is capable of producing some of the best results that can be achieved from ultrasonic cleaning. My Audiodeske takes around 7 minutes to complete a basic cycle which includes 1 minute ultrasonic cleaning time, the rest is drying. I usually extended this to 2 minutes cleaning so the cycle was typically 8 minutes overall. With the RW-800, I use a standard 2 minute cleaning and adjust the power depending on the degree of cleaning required. Drying time is just one revolution of the record because it is vacuumed from both sides simultaneously . Of course with a fully automatic RCM. you can leave it and walk away and it will dry the record automatically. Except that with the Audiodeske if i left the record too long in the machine after the cycle had ended, there would be moisture condensing on the record which had emanated from the close-by wet rollers. Ultrasonic cleaning in progress. The record is turned by a direct drive motor in the support column and operated by a switch. Vacuum drying from both sides simultaneously - Just one revolution will do it. The machine weighs around 35 kg and is big. It has an industrial quality feel about it and you can quickly clean a few records in a row in no time. The tank is designed to be emptied in situ and Amari provide a tube system to direct the waste into a container. The cleaning and vacuum waste water is released via valves operated by switches on the front. Every component in the RW-800 is easily serviceable which is a welcome change, but there is little that can go wrong with it and the vacuum system has been proven through thousands of units already sold in the company's range of RCM's. I bought this at the same time as another Perth SNA member and we paid around $1500 each for the machine delivered to our doors. $280 of which was air freight from the Singapore dealer where we bought it from - this is a big , heavy unit. The dealer has visited the factory and was very helpful - useful in view of the very basic English manual provided with the machine.
