ross flanger with 220v input

[Gstring]

any easy way to convet to 115 vot-output is 48 volt

Que?

could you rephrase that!?

I have 3 nos  ross flanger-problem they are 220 volt for european use-I want to convert them to 115 volt-the out put is 48 volt split 24 volt  center 24 volt-any ideas-thanks

Whatever you plug it into in the wall, the Ross will more than likely not be feeding the BBD and op-amps and CMOS chips on board with anything more than 15v, and quite likely 12v.  Whatever you have to do to send that supply voltage to the chips wherever you are, do it.

buy the appropriate power supply would be the way I would go.

You should be able to find a 115VAC to ±24VDC supply.

Converting the 220V one is probably not an option, unless you can easily swap the transformer for one rated for 115VAC. The rest of the circuit should work as long as you feed it the same secondary voltage.

But, like Mark said, sounds like a lot of voltage! are you sure that's the original power supply that came with the flangers?

Places like www.jameco.com have cheap little 230/115 transformers. I'd just get one of those. I'm in Australia & have the opposite problem (110v boxes) so I run a stepdown & a USA plugboard. I don't like modding fx, especially if 'vauable or rare'.
