Vintage Precision Power Supply Teardown

at 6:34 am. Filed under Insane Equipment


Our friend Dave from the EEVBlog took apart this Vintage Precision Power Supply. With a quick look at the front panel you might think this is something that you would have got from Radio Shack 40 or 50 years ago for your hobby kit but this is a 0.001% precision power supply! It was designed by Power Designs Inc of New York back in 1964. When you see the internals you will see lots of point to point wiring which was popular back in the day, these days you only generally see point to point components bodged onto cheap Chinese equipment. The condition of the internals is very clean considering the age of the device! Unfortunately a simple adjustment of the trim pots wasn’t enough to calibrate it. I am assuming that some of the crusty old caps are desperately needing replacement.
