@amonv: Do you have a link for that?

from this link, http://www.metaxas.com/pages/products/solitairex.html

1. INPUT STAGE: The fully complementary, dual differential, cascaded input stage is linearised to ensure least distortion over the large voltage swings to the amplifier input from the preceeding preamplifier. A very gradual (6dB/octave) Bessel filter is incorporated at the input to eliminate the needless reproduction of Radio Frequencies.
The second voltage gain stage uses considerable local feedback to ensure that large voltage swings from the input stage are accommodated with the least possible distortion.
An overall negative feedback of only 11dB is required to stabilise the complete D.C. operating point and reduce distortion at full power to below 0.1% T.H.D. which is primarily composed of second harmonics.
A D.C. servo is built around an integrated circuit to monitor the output voltage and ensure absolute D.C. stability at all times.


sorry to rain in your parade, the adds got me thinking, a fully complimentary solid state amplifier is also a push-pull, therefore 2nd harmonic is largely cancelled, this is a typical advertising designed to give tube attributes to a solid state amp....

Thank you Tony for the info... :sweat: :sweat: :sweat:
