Have you opened the P1/u to see the insides? I ask this because afaik Luxman is only producing 100 and 120 Volt units for the Japanese and US markets. However someone, I think it was at HF, said the trafo had different primaries, so it would be possible wiring it for 230V operation. Were that true, I'd seriously consider giving this amp a try. Any information about this issue will be very welcome.
