Greetings all...

Right behind my head on the 737NG is a pair of electrical outlets. One is 115VAC at 400Hz. There is also one in the galley that our FAs use to charge the credit card processing machine they keep on the cart.

Does anyone know the specs and/or where to get something that will "step down" the 400Hz to 50/60Hz?

I checked at my local radio shack and found no help there.

Thanks!
