I would need to know about Bar and PSI. What is the relation in this two i want to know details.The power supply shown in the picture has steadily been getting weaker, and I hadn't really noticed because it was so slow. It is almost 30 years old, and home brewed. The max it would put out before the regulation would shut down was 0.1A, and it should have been almost 2A. When I opened it up I saw the PCB shown below, it had baked itself pretty thoroughly. It was a Radio Shack PCB they sold way back when that I modified for my own use, leaving off a lot of unnecessary parts. So I laid wire to replace most of the baked out traces (which were more oxide than metal) and it worked like it used to, though it was incredibly ugly. Even one of the #6/32 screws used to hold the TO-3 case style LM317K was corroded, and replaced.
Sometimes having the right piece of equipment is just what you need.
