Hi 1 I could not find any hints in the service manuals (even BG 4002 type 5501) where is discribed to change the fuses to 500 mA, so I would keep the 250 mA slow blow and check it out. Of course the Ohm's law says half of voltage means double of current with same power output = 500 mA Maybe Martin has further informations from Service manuals which I've not seen. The worst thing what can happen is that one of the fuses is blown and the Beogram stops working. Tonearm will lift at power fail.   2 Regular glass fuses, slow blow 3 Living in DE so no experience 4 you could use an adapter or mount an UK plug as you like, I would use an adapter so all keeps original. The plug should have no effect to the sound because there are no RIAA amplifiers or somthing active parts like that in a BG 4000. The High end authority would say something else ;-))   Kind regards Christian

Thanks for the reply. I opened the fuse box to take a look. I think I’ll order a few at 0.5a and just keep them in case. I’m not ready to turn it on yet as I am not in the final region but here in the UK the 4000 is working perfectly.
