Converting Mark Levinson gear from 240V to 120V

Can anyone assist me in converting an ML 23.5 from 240 Volt to 120 Volt? I see a series of blade connections where the power wires converge with 2 jumpers. I'm sure it's a matter of moving/adding/removing these jumpers.

I also have an ML 30.5, 31.5 and 38S. These look like they have to go back to Madrigal for some surgery to make the change, but if you know how to do this, any help would be of great assistance.

Send it to Madrigal, please. That is what they recommend (if it was safe or easy, the procedure would be in the owner's manual). Poking around in power supplies of hefty SS amps is deceptively dangerous.

Respectfully, and with no offense to anyone, I would not trust any advice on this matter unless it's from a qualified technician.
