Found the PECs, which was about all I could do today, as family demands occupied my time. Also noted their places in the schematic.

It is interesting that the majority of the circuit is laid out with discrete components, yet these small building blocks were used in filter and tone circuits. I wonder what the motivation was? Cost? Better tolerance? Convenience?

I have no plans to change these parts in the near term.

As to audio purists, I find a lot of that world to be particularly obtuse, if not nonsensical. So many "philosophies" and clique-ish behaviour. Not to mention a significant layer of pseudo-science. I'll have no truck with that side of things. Over the years, I've built many a piece of audio gear - solid state and tube amplifiers, designed and built a CD player DAC, and a phono preamp. Not to mention things restored and repaired. Basic principles, no nonsense, good sound. I don't care about the whimsical affirmation of hifi purists.

When it comes to radios, however, I do pay close attention - especially to folk here. It is obvious to me there is a great deal of experience, skill and knowledge displayed among the forum members, and comments on my projects are taken very seriously, and in good faith.
