Converting Mark Levinson gear from 240V to 120V

Why not run a dedicated 240V line from your electrical box? Simpler and the equipment would probably run better anyway.

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.

When I worked at a ML dealership I was told by the ML rep. that it was done to protect the dealers and distributers from "gray market" goods. Not to mention the safety issues. I can understand this after feeding my family by selling hifi gear. When you spend hours with someone educating them about a piece of gear and then they buy it from an overstocked dealer, it hurts. I have been out of retail for four years and don't miss it at all. I do miss many of the music and equipment nuts that I became friends with though. All in all, it was a great way to make a living.

Hifi I agree with you they should buy from you, if
you spend time teaching them,I would love to go
to a dealership where there is a salesman like you.
Unfortunately and sad, there are not that many salesman
who knows, How to treat costumer, Not trying to hijack
this thread.Agon is my best dealer.

I've converted my 20.6s from 110v to 230v. It's was not done at the factory though (too expensive including shipping and not forgetting a 6 weeks waiting time) but by my trusted hifi technician. The circuit is at the front of the unit (you'll have to open the cover). He did some measurements, swapped the jumpers as well as flip a switch from "low" to "high". Viola...it's been more than 1 1/2mths now and no problem encountered. The conversion should be similar to the 23.5. Just look around...happy listening!! Cheers.
