I've just moved from UK to Trinidad, where electricity supply is 110-120V at 60Hz (some of the time...it's a little muddy). Can anybody recommend a good audio-grade step-up transformer block with voltage regulation?

I was in a similar situation many years ago. At the time I wrote to the manufacturers of my UK eqpt asking that very same question. They all advised against using a voltage transformer and, instead, sent me schematics on how to convert the eqpt for 110V use. In some cases, it was a simple matter of moving a fuse or two, in others I had to move some wires on transformer taps by cutting and soldering. Nothing dramatic and all fairly easy.
I had the same problem when I moved to Boston. I don't know how it works in Trinidad, but in the US the power enters the house as 220-240 Volts in 2 phase. It is then split into 2 times 110V. I had a dedicated 240V audio outlet made by an electrician (who thought I was crazy), but it worked perfect. Talking to Audio Research, they told me they had the impression that the VTM200 mono amps -I had back then- sound better on 240V.
