power my Neve 1272 with the Api Lunchbox supply ?

Hi Guys , I want to mount my Neve 1272 in some way into my Lunchbox.

What's a proper way to get +24v from the +/- 18V Api ?

thanks

I think he was trying to say that if you step up to +24V you'll damage existing modules in your lunchbox.

And what if I use a regulator powered with the (+ and - 18V in series) 30V ?
I was thinking more in this direction

It won't work because once you connect ground of the 1272 to ground of the lunchbox, which you must do, there's no way to get the +24 volts you need.

To explain this another way, if you tried to do it by connecting the two 18 volt supplies in series, the fuse on the lunchbox would blow as soon as the ground of the lunchbox was connected to ground of the 1272, because you'd be shorting the -18 supply to ground.

Possibly the unregulated side of the phantom supply could be used to run a 24 volt regulator, but it would be a bit klugey and inefficient and might stress the lunchbox supply. Really, the best thing would be a small, dedicated +24 supply.
