The main disadvantage of push-pull class A amplification over single-ended class A, is the necessity for a phase splitter stage to generate the oppositely-phased drive signals.

From a guitar amplification standpoint, neither class of operation is necessarily better, they are just different.

We hope to develop a method to assemble a new class of turbine-like aggregates, and then investigate their applications in molecular recognition, supramolecular chirality transfer and amplification.
