Jameco P/N: 20626. Watch Collin Cunningham as he assembles the Adjustable Regulated Power Supply kit and learn a few basic principles of power supplies while you're at it.
Except in my case, I need a 130VDC source to trigger a coin relay in a Western Electric 1D2 pay phone. Yes, I know I can modify it t use a lower voltage but I want to keep it original.
Line voltage here is 125VAC (I've measured it!). So a 1:1 isolation transformer into a bridge rectifier and sufficient filtering caps should give me what I need.
ok this dude looks like a hisetic Agent smith. "Its the smell , I mussssstt get out of here."
