Reverse-Engineered! - Elka F000445
Mar 8, 2025
Reverse-Engineered! is an article series where I look at random small pieces of electronics.
What is it
The ELKA F000445 is a flute filter.
I was able to find references to these parts being used in the Elka Artist 707.
7 different variants of this circuit have been used 3 times each for a total of 21 of these PCBs in each instrument.
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.
