Help:ampeg svt 2 pro 100v>>240v

[jujumusic]

I purchased one AMPEG SVT II PRO amp head in japan.This AMP voltage is 100V. China's voltage is 220V.

I want to change the voltage to 240V.

I only found original SVT II jumper method,But they are not the same.

Who can help me.

Many thanks.

Find the email for Ampeg tech support and fire them off an email. I sent one to them (would be 18 months or more ago now) and I got a quick response and clear instructions. By far the easiest method and they know what they're talking about.

One way to do it is to use a Variac and supply 100V to operate it. Then measure the voltages on the various primary taps until you find a pair close to 240V. Those will be your new input power connections.
