Anyone up for Transformer Rewind?

[Watthour]

If there is space to mount a 2½" cube of copper and iron under the plinth, a bucking transformer could be installed there to supply the table at 100V. If not, an external enclosure with plug and receptacle should get it done, although it would be a little more cumbersome. If space is available, a Newhouse 40TR or something similar should work. The connections would be as follows:



If the transformer is not marked for phase (and it probably isn't) you can try a connection on the bench, not connected to the turntable. Apply the line voltage and measure the resulting voltage. If the secondary is in-phase with the primary the resultant output voltage woould be something on the order of 145-150VAC. If the secondary is out-of-phase with the primary, the resultant voltage would be around 95-100VAC.

Get a request in to edcor. They make these things from scratch and will probably do so for less than the cost of shipping it to a rewind facility. I'd pull out the old one, mount the new one in its place and keep the old one so it can be put back to stock If desired.

I asked Edcor for a custom transformer quote one time. I ended getting the transformer made by Heyboer if that tells you anything.

Why wouldn't one of those step down power supplies work? Lots of them for sale. Many have a switch to select 100,110,120v,.etc. output. Some switch the primary voltage. Just plug the box into the wall and select desired output voltage.

This is my solution for the same situation, have a Japan version of the Denon DP 75. Believe mine cost around $25.00, it has 2 outputs, a 100 volt and a120 volt, and it’s fused. Power it with the switched output on the preamp, no issues.

I get it, it's an extra added thing to plug in, but doesn't involve modding anything.

I asked Edcore about building a couple output tranys. It was the same as one they have listed, but I wanted a different UL % tap.
Thay wanted over $200 just to have someone make them. That was on top of the price for them.
