I currently have 1 UT110W and 1 UT130E for sale, both are used yet in good and of course working condition.
I received mine today, thanks!
My GT always made a humming sound.. I always thought it was something loose in the machine itself..
But now it's gone!
I used a generic us step down converter that gave 117v. The new one just 103.. much better!
That’s awesome! I think clear evidence that it’s better for the machine.
I measured my UT-110W and UT130E inventory and all are about 102V-103V without load and drop only 1V when load is a Panasonic FS-5000F2. My mains voltage is 220V (I was finally able to test this 
)
I have also ordered a Kashimura transformer, these are a Japanese brand but made in China. Now we all know a lot of Japanese companies have had electronics made in China over the years and if the design is Japanese and the QC is good it does not necessarily have to be a bad product (it is still sold in Japan by a Japanese company, so their cultural rules of supplying a good product would still apply imho), it is a 200W transformer (model TI-200) and it is a used one but I liked it for comparing the quality to the made in Japan transformers....
