I have already understood the OTL circuit. Baidu Encyclopedia said that this is an upgrade of the OTL circuit, eliminating the need for output amplifier capacitors, making the system's low-frequency response smoother. I hope you can help me analyze this circuit.

R6 is not current-limiting, it is mainly shunting, and it divides the current of the base of Q6 and Q7.

R7 and R8 can be regarded as current limiting, connected to the emitter to limit the collector current.

D1 and D2 are not only the function of eliminating crossover distortion, but also temperature compensation.
