I have an old Motorola DC power Supply. At first it would not power up so I changed the power Transistors (4each) on the back of the unit. Now it powers up and gives me 62 volts DC output with no control of voltage or current control. Can any one point me in the right direction? Maybe even a location of schematics.
There is a book, "Electronics for Inventors" (check Amazon), that will give you the basics of power supply design and electrical components including general scematics. Without more info on what the PS is supposed to produce in the way of voltage and current, there's not much more to be said.

I have a Motorola phone base that is missing its power supply. It is a Motorola Iridium 9570.

I have been unable to locate affordable power supplies for it and
universal adapters do not work because of the unique socket on the
phone base. Is there any kind of universal adapter or socket converter
device for it? What kind of socket is this and what is called?
I managed to get pictures of another power supply for this phone.
