Answer by Andy aka for Transistor Based Amplifier and DC Only Negative Feedback
Wouldn't the lack of negative feedback (at AC) make the AC signal prone to all the usual distortions that NF is supposed to solve? That circuit is for driving a moving coil meter. The overall idea...

Yes, R48 and C17 form a LPF at about 16Hz, which clearly makes that a DC path (since the main oscillator for the RLC bridge is going to be higher than 16Hz). However, there is an AC feedback path back...

Transistor Based Amplifier and DC Only Negative Feedback
My analysis of Heathkit RLC Bridge continues (previous question here). This time I've been trying to analyze the feedback amplifier section shown below and taken from the original document IB-5281...
