will be impossible for a non-industrial person. The return phone call will be interesting.
As I stated in a post above, I hate to dispose of machines, especially this stainless ultrasonic machine designed especially for phonograph records. 18 years ago, I had never seen anything like it. However, in Taipei at the same time, I had seen the prototype machine pictured below. It sounds similar to the description of your two sided vacuum/ultrasonic machine. It was located on the second floor of the electronics center at the intersection of Hsining and Luoyang streets.
I do have a good ultrasonic setup at my other location in the state of Washington. See the picture below as well.
Thanks again for everything. Bill.

The tech guy says that there are certain things that needs experience to bond the transducer plate to the tank, not impossible for end user but if something went wrong, the plate is easily to break again. He did not specify which step needs extra caution though.
First of all, one needs to remove the old plate, this is probably the most laborious part of the work. Sand smooth, cleaned and ready for the new one. He also mentioned that one has to be sure that the electronic part is fully working. Using ab glue, heat gun to soften it a bit and apply the insulation, then the plate. I don't know exactly what he is talking about, just repeating his words here. I guess the flatness of the bonding site and full contact of the plate with the tank are the important things to watch for. Good luck!
what is meant by the insulation. And yes, I can imagine removing the old glue will be fun.
If the electronics are for a frequency of 43KHz, then I will try to find a close ceramic transducer.
Well, this will get me started, and I am very thankful. I certainly enjoyed my time in Taipei while I walked or used the buses to visit all the hifi and electronic stores. My closest acquaintance in Taipei was Mr. Rudy Tu, who owned Sincere Electric Company at No. 61 Sec. 1 Ming Chuan East Road. I believe he retired and moved close by at No.63 Sec.1 9F Ming Chuan East Road. He is the person who drove me to the ultrasonics factory.
I don't know exactly what it is either, I can only guess that there is an insulation sheet that comes with the transducer plate to prevent electrical hazard if things go wrong.
Sincere was a very old audio shop, I know where it was but never been there before.
No problem for the phone calls, it's what a forum meant to be.
closed his business. I once tried to help him fix a customer's Forte amplifier that caught fire, but Forte would not cooperate with me. I was able to purchase a large container of a spice in Alaska that he wanted, but no help with hifi. Mr. Tu always had music playing on his AR-XA turntable, but I forget the amplifier and speakers. He mostly serviced equipment he had previously sold and had very little new things for sale. There was a great CD store close to him that sold audiophile quality CDs.I just realized that the ceramic transducer must be insulated from the stainless steel to prevent a short between the bottom of the transducer and the stainless steel wall. I don't think the transducers sold online provide an insulating material. That's something that I may still have to research and may need that one last answer from the company in Taipei. I believe the insulating materIal must be rigid instead of flexible.
I have researched how to remove the old transducer, and I feel confident that I can do it.
I also purchased this excellent vacuum cleaning machine in Taipei at a store near Zhongxiao street and Luoyang street.

No problem, will keep you posted.
Yes, Mine is the one with the green LEDs. The construction is not so sturdy but the man who made these machines keeps running free maintenance island-wide, including free changing of the sucking pads. No doubt about his devotion to these machines.
