What is a pyramid schemes?
Hi Linda, It's called a pyramid because it starts with one person putting money into a fund, Say it's a guy, He then invite as many people as he can(say 10) to do the same and then those 10 people invite as many as they can(say 10 each x10=100) and so on100x10=1,000) and on(1,000x10=10,000)... see how it grows... And what happens is the 1st guy gets a percentage of the money from the 10 people he invites plus a percentage from the 100 people they invited and it goes on and on, , the people he invited get a percentage of the people they invite plus a percentage from the people they invited and so on and on and it just keeps going and going and the higher on the list you are the more money you get but the lower on the list you are the more you struggle as it gets harder and harder to make money because everybody above you on the list are all getting a percentage from people all down the list until eventually everybody on the bottom of the list looses all their money and that's why it's *******......DO NOT DO IT, If you make any money from this scheme just know it's from people loosing theirs, Take care.........
PS36K power supply overload problem
Most of Pyramid's supplies are based on the LM723 voltage regulator. The
DATASHEET should tell you most of what you'll need to know to repair it.
THIS is the schematic diagram.
If the output voltage drives the voltmeter to the end of the scale, it likely has one or more shorted power transistors.
