BigMac, Unity coupled output amplifier
http://www.veiset.net/unity/index.html
Unity coupled output amplifier. Unity coupled output amplifier (ala McIntosh) with 2 pairs of EL86 as output tubes. One of two mono blocks:. Working conditions are 260V B , 190V Bg2 (regulated) and 90V for the negative rail. The amp runs near to class B, biased with 4 x 10-20mA in the output stage. Max power output was estimated to be about 30W and I measure the onset of clipping at 15Vrms into 8.2R ( 28W). Schematic: front end and output stage:. Results achieved with 10dB global NFB:. O Zo : 0.8 ohm.

Hyperlinear Preamp
http://www.veiset.net/Hyperlinear/index.html
The term "Hyperlinear" referes to the feedback loop from the cathode follower back to the input pentode s screen grid (g2). Due to this feedback loop the input pentode is more or less working in triode mode, but the connection between plate and g2 is extended to include the cathode follower. This reduces the overall distortion and lowers the output resistance of the CF. Some measurements with 6SJ7G and EBC33:. THD: 0.05% at 1V rms output. THD: 0.5% at 10V rms output. S/N: 78dB ref 1Vrms output.
