Ok that was in bad taste!

Very funny and rather correct. With the way my body is slipping/sliding down-hill, even a "mechanical" night means I deserve a medal. And boy do I pay for it the next day...

I wonder if that troublesome spanner that built the 2nd story extension via the neighbours picture window that blocks the view of the water could be pressed back into service to put the wheels back on the B4 project.

B4, not after?

Burning Amp #1 is your New Years gift, although it is waiting for the
revised site to be launched - in a few days.

Maybe it will be for Valentine's day...

Yes, but it would certainly have to be more complicated than
the JFET follower of the B1?

What is the application?

The main application would be to have 2 buffers , one of them invering polarity , to drive balanced inputs , without building a differential pair splitter . Is it probably better to imagine a differential pair with gain=1?

And also to have a spare inverter for sound test in various configuration.
