The power amplifier comes from an antique TV / radio / turntable combo.  Originally built on germanium transistors.

Interesting, I don't think I've ever seen this topology before. It's like a hybrid between Pseudo-complementary and tube-style push-pull. Where exactly is this curcuit from?

Also interesting it uses a bipolar PSU instead of just an output coupling cap

I don't remember the device model this amplifier comes from. A few years ago, a friend of mine gave me a stereo amplifier board on a metal frame that looks like the bottom of a tube amplifier, with a hand-drawn diagram from his book or brochure with the information that if I want to, I can try to make a working amplifier out of it, or throw it into the bin.
