OTL Asylum

Posted by 6AS7_6SN7 (A) on November 06, 2009 at 03:53:27

The Japanese engineers of Technics had studied a peculiar OTL type that, to my limited knowledge, has not been mentioned in this forum in recent times.
I have revisited the original topology (see schematic, where the tube count is the same as the last posted "Modified Futterman").
The overall feedback in this case is 6 dB.
Simulated spectra will follow.
