Hi,

The design is simple.

First, the output is not fully short circuit proof.

It normally survives a probe slip, but a permanent hard short on the output and full voltage on the input will fry it crisply, with Mosfets and several other components dying.

Second, the "track low point" simply means that the circuit will always drop out as little voltage as possible.

Drawing too much current without a bigger input cap may again create too much heat.

The 2008 versions had a "bug" in the negative supply. I cannot remember which particular connection triggered it, but I seem to remember it was with centre tapped transformers.

Otherwise it is normally quite solid. It just does not like to have a permanent short on the output, which may happen with mis-wiring.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
