Reverse-Engineered! - Elka 410CST0811 / Elka 99-19
Mar 8, 2025
Reverse-Engineered! is an article series where I look at random small pieces of electronics.
What is it
The Elka 99-19 and Elka 410CST0811 are amplifier PCBs. The Elka 410CST0811 seems to be a later revision of the Elka 99-19.
I found references to the Elka 99-19 amplifier being used in the Elka Capriccio 33/OL from 1774 and the Elka Concorde 100 from 1977.
So far, I have not been able to find any reference to the Elka 410CST0811.
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.
