Help in design: adding a Baxandall diode across emitter in Quasi Complimentary Stage

[Mooly]

That's quite an impressive list of mods. Well done 🙂

Just because stuff is old, it doesn't necessarily follow that caps are automatically bad. I've some Sony gear from the 1970's and its all original.

You should be good for another 40 years now 😀

I wonder if as many of the "new" capacitors will perform as well after 40years.
