I'm not clear - Did you want to configure Z4 as a follower? If
so, there are already some nice Source follower circuits out
there. Z4 is not set up as a follower.
On the other hand, Z4 has an input follower in the form of the
P channel Mosfet. This dramatically raises the input impedance
of the amp for those with girly-man preamps unable to drive
600 ohms.
BSOZ is perfectly happy driving either situation. If you want to
use it as the voltage gain stage, consider two followers in
balanced input and output, and you'll get twice as much swing.
Re: Tank you
Easy enough to do. Just use the N channel current source
from the positive supply like the rest of the Alephs, and
use it to bias a P channel Mosfet whose Source goes to
the current source and the output, and whose Drain goes to the
negative supply. Drive the Gate of the P channel, and voila!
