Unfortunately, following direct links on the channel does not work, until we fix it over time.

As additional studies have shown, the Dual 440 achieves its parameters in a pure FOS. The original circuit is rather non-linear and the first pole of the frequency response falls into the audio range.
Kg without environmental protection, the output is still in "A" 0.25 +/- B "AB" up to 1%. Naturally, Ku and the depth of the OOS are much greater than those of my version.
My version of Lynx 11 has an "A" without OOC of 0.001%. And in "AB" without environmental protection increases to 0.28%
The first pole is in the region of 40 kHz.
This is the picture of the original circuit.
