RX02 115VAC/60Hz -> 230VAC/50Hz

Hello list, I have the possibility of acquiring a RX02-BA 115VAC/60Hz standard North American power. I have a couple of questions concerning the feasibility of a power conversion on it. After studying the schematics of H771 of the RX01/02 units and the manual, there are 4 things to do for a power conversion: 1. Replace H771-A with H771-C or H771-D. 2. Replace power harness 3. Replace belt and pulley 4. Replace circuit breaker Here my questions: 1. From the schematics, the difference in H771-A and H771-C or -D is the transformer has no center tap on the US supply. Does this mean that there's no way for a DIY conversion job? Or it just mean that the transformer does have a center tap and it's just unwired? 2. Power harness is no big deal, I can just make a new one. 3. Belt and pulley; this is the tough one. Calling UK list members: anybody has spares? 4. Can the circuit breaker still be bought in electrical/electronics supply stores? Thanks. /wai-sun
