Elka 410CST0811 / Elka 99-19

March 8, 2025

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.
