In 1998 in Taipei, Taiwan, I purchased an early ultrasonic cleaner specifically designed for records(see pic below). I used it only a couple times, then it sat in my basement for about 18 years. Yesterday, I dug it out to see if it would clean what appeared to be a couple very small paint deposits on a record. The deposits did not respond to surfactants, alcohol, or enzymes that I normally use with my Nitty Gritty 3.0 vacuum machine in Alaska. When I set up my ancient Taiwanese ultrasonic machine, the unit had the usual vibrating noise I was used to. However, there was an additional clacking type sound. After a few minutes of use, a high pitch sound began that continued to get worse. It sounded like something imminent was about to happen, so I shut down the unit. This was very disappointing, as I have rarely used the machine. I received no information about the machine from the manufacturer, and I didn't really know what to ask that long ago. The only specification known is 110V and 2 amps. The transducer frequency is unknown. The Taiwanese manufacturer only made a few of these record cleaning machines, as their primary products were large, industrial, ultrasonic units. When I opened up the unit, the circuit boards all looked good(se pics), but I noticed one of the piezoelectric transducers was cracked. This machine has never been dropped and has sat unused for at least 18 years. Anyway, I sure would like to resurrect this ultrasonic cleaner, and the transducers are very cheap. I would like to purchase a similar looking 40kHz transducer, but I don't know how to match the new transducers with the circuits now in the machine. It may be very difficult to even remove the bad transducer, and I don't know what adhesives are best for attaching the new transducer. I cannot think of any local businesses that could handle it either. The transducers are so cheap, that I would like to get it repaired. As you can see, the unit is totally manual, but it did a good job years ago. Right now, it is just a museum piece for a record cleaning museum. |
