by Marty Houlroyd I feel my age when bringing up the names DataCon and Mupac, back in the 80s and 90s they were the leaders in wire-wrap technology. At that time, I worked for a little no-name company that tried to compete (mostly miserably) against these industry giants. Some wire-wrap applications, especially telecommunications. used giant […]

How to build a power supply with two different output voltages
by Electro-Tech-Online forum member Crutschow The schematic to the right shows a simple way to get two full-wave rectified voltages from one center-tapped transformer winding and one bridge rectifier. Adding a capacitor filter at the center-tap gives roughly half the DC voltage from the center-tap output to ground as compared to the bridge output to ground. This […]
