I was wondering what is involved in changing the input voltage on a Beomaster 8000. I am have one sent over from the states (late night EBay session!) which will be 110v. Do I need parts out of a donor 8000 with UK spec, or are there modern components available to renew the input. I would rather it was all tucked away internally in the unit than an external device.
As always any advise much appreciated

I am guessing you will have to use a step down transformer. The US and European owner manuals specify the Beomaster 8000 supports 50 and 60 Hz cycles but the voltage levels are fixed for those markets (don't appear to be switchable). I don't know if you can change the wiring of the power supply to the transformer or not. The transformer on those receivers is the heaviest thing I have encountered in a piece of audio gear. Hopefully someone on the forum has done that before or knows for sure whether you can.

Anyone??? surely I'm not the first (or last) to have a tiny EBay flutter after an evening of wine and ELO. The amp has arrived with the engineer for some other work, so any help re: conversion would be much appreciated.
As I read the service manual, only Beomaster 8000 type 1907 is switchable (or rewireable, the schematics don't show) between 110/220 VAC. The other three types (1901, 1903, 1905) are fixed at 220, 110 or 240 VAC.
If you have any of the latter three, the only options are a step-up transformer or replacing both the main transformer and the standby transformer in the Beomaster to a type that is compatible with your local mains voltage. All these four pairs of transformers have different part numbers.

Many thanks
its a 1903 so it looks like some swapping is needed...can anyone tell me what parts are needed, possible suppliers? in the UK?
