Switch voltage of Lamm ML2.2 to 220V

I have moved my Lamm ML2.2 oversea and have no chance to send them back to Lamm Industry for voltage change. I have a local expert to open the amps but they look not simple to switch the voltage from US voltage of 120V to 220V as the manual mentioned. I have emailed Lamm but got no specific answer on the issue.
I would be thankful if anyone know how to change the voltage and let me know.
Tks

Hi Erik,
Thanks for good advice.
I already use a step down transformer for the Lamm monoblocks but I would still prefer to switch the amps to 220V to feed directly from my Audience AR12 power conditioner that suppllies power to whole system at 220V.
Cheers

I managed to switch my Lamm ML2.2 from US voltage 120V@60Hz to Vietnam voltage 220V@50Hz. It was just three jumpers and a pair of cable swap. Anyone with the same need please let me know for detail. Lamm Industries would not tell you how to but ask owner to ship the amps to their headquater for the simple twaek that would mean huge cost of shipping for one who moved oversea.
