Is it possible for Aleph to operate in class a/b or b mode?

Just wondering if somehow the Aleph 30 can be operated in class ab or b mode???

Yes, but it's not pretty. If you increase the gain of the current
source without increasing the bias to follow, you can drive into
AB, but being a simple circuit, the nonlinearity of the current
source shutoff is prominent on current peaks.
