Rather than modding the amp, you could try an external Step Down Transformer.

Step downs are the best way to use US gear here. Go to Jaycar or Dicky S and they should have something appropriate for your purposes.

I don't know...If I'm carrying an SVT around, I don't know that I'd also want to carry a box the size of a car battery that weighs as much as an SVT, too! I'd replace the PT myself.

Since somebody mentioned the transformers sold by Fliptops, it might be worth contacting them to see if they have a more legible schematic. From their description, it looks like their transformers can be wired for 120 or 240 V.
