Speaker circuit for the 38-7

Thanks, I was wondering about that. It seemed ironic to be using the speaker magnet coil as a choke to reduce ripple for the B+ to reduce 120Hz hum on the sound, only to be sending that alternating current right to the speaker.
I am impressed by all the clever ideas that were developed to optimize these circuits.
