Reverse-Engineered! - Elka F000406

Mar 6, 2025

Reverse-Engineered! is an article series where I look at random small pieces of electronics.

What is it

The ELKA F000406 is a full bridge rectifier and linear voltage regulator.

Two of these PCBs have been used in the Elka Capriccio 33/OL generating the +5V, +12V, and +22V voltage rail.

Why do I have it and where did I get it from

This PCB is one of many analog synthesizers and organ parts I acquired at an auction about 15 years ago.
