As the title says...can you rewire a 220 volt amp to run on 120....if so, how hard and costly?

you can if the transformer has 2, 110v windings

Lewis Moon · 18th February 2009, 01:07 AM

An MB Quart 200W plate/subwoofer amp.

Unless you have the schematic you'll have to hook it up to a drier outlet and measure the transformer secondaries. And take physical measurements too. Probably be 50 bucks or so, is it worth it.
