Thx alot Josep !!!

Yes, I noticed the missing upgrade from Duncan's side :-) No hum in my monitors.

The transformer looked from memory a bit smaller than the one of my 565, so I started to wonder, if that missing winding story was really correct.

Unfortunately I had my 565 already closed and could not directly compare anymore and who likes to rip his system apart all the time. I have access to two technicians, will try to consider the modification, as I guess now I'm forced to take that challenge up ;-) Will need a few more fuses for 250Volts then. So I will give it a try, give me some time to check. If I run any risks I won't and in the end, if it can be done, it should look clean, professionally soldered and wired as well.

Hi Josep,

I think it worked out. Time will tell now. Thank you once more. If the unit will "survive" what I did, took 5 minutes indeed...it even shows once more how one can be "lost and caught" in the wisdom of distributors.....anyway.

Well done, and nice detail the removal of the 115V sticker too! smile

Maybe it is worth to save the pictures around here (Wiki?) for future reference?

Maybe someone can change the thread topic into "from WTB to DIY, 561 transformer voltage conversion, from 115 to 230 Volts".

@Virus: blame M, no "spare stickers" came with the machine smile Also for the amount these units once cost, I still do not understand why there is no part for automatic voltage switching inside, so that the powersupply would be 115-230 Volts.....well, anyway, 5 series is sort of history.....case closed.

EDIT: and once more thanks Josep !!!
