Rob, that's reassuring...I'm sure I could get away with a 240 volt supply, but I'm not sure how an increased supply would affect the plate voltages on the output tubes (which I think run at about 12-1400 volts)...I just reckon caution is justified (although not so much caution as not buying the things in the first place!)

A transformer will increase the output by the same percentage as it's input has been increased, so a 10 volt increase on the primary to 230 will equate to a lerger voltage increase from the secondary, if the secondary is putting out 12-1400 volts allready it would increase by about 50 volts "allegedly".

Buy some better valves just in case.

Watford valves are a good source.

Agreed, Watford Valves are an excellent emporium....Plan is to replace the valves with Euro/US NOS before even turning the things on (which will immediately double the cost). Then get audio legend "The Cartridgeman" to wave his magic wand over the internals (which will quadruple the cost)...the aim is to get "Desmosedici sound" for "Monster 600 Dark price" ....if it all goes horribly wrong, i'll wait to February and sell the things as ancillary room heaters.
