Apple-1 external Powersupply "the Powerbrick"  
 Users in European Countries that built a Apple-1 replica have one problem:
 The transformers used at the original Apple-1 have been made for 115 Volt powersource in the U.S.A. while in Europe the most countries use
 220 Volt. The User therefor won't be able to used the original Stancor transformers. So the user has two options: Search for european version
 of transformers that look alike the Stancor transformers or instead use transformers with nowadays technology.

 While the first option is a quite time eating task the second option again itself offers 2 alternate possibilities:
 Use very compact ring transformers or use also very compact so called PCB-brick transformers. I made 2 supplies with both options.

 While in the cases with mounted Apple-1 PCB i used the ring transformers as "internal" powersupply because i didn't want a Prototype PCB
 besides the Apple-1 PCB in the case i also made for use of the Apple-1 mainboards outside of the case and for testing purposes a "external"

 powersupply that i call "the powerbrick" because it's nearly same size like usual red brick ( 17 cm x 10,5 cm x 5 cm ).

 It's rather simple "homebrew" mounted at the standard "prototype PCB" ( 10 cm x 16 cm ). I use 2 PCB-brick transformers and added to

 each transformer at the primary side a fuse and at the 2 x  6 Volt transformer 1 x 3,0 ampere  furde and at the 2 x 12 Volt at each 12 Volt output
 a 1 ampere fuse. And because i want to see if supply voltage to the Apple-1 is OK and no fuse got blown away i added to each line at the
 front face of the supply a green LED indicating the status of that line.

 The current that is used at each line for indicating status of the line by rectifying the small amount of voltage used for the LED is less than 30 mA.
 The entire rest of the voltage remains AC and leaves the case towards the plug.
