Jolida 502b conversion from 110V to 230V ?

Hi all,

has anyone ever tried to convert an older (gold front plate) Jolida 502b from 110V to 230V. I've tried to get Jolida to give me details regarding what would be required, but they seem pretty sluggish to respond. I currently live in the States, but am returning to the UK soon and want to take my Jolida with me. I've read a bunch of things, partly on this forum, regarding poor sound quality using a step-down transformer to power the amp. Thus I was contemplating a conversion.

Any thoughts on this topic would be greatly appreciated.
