A Universal Shunt Regulator for Audio Applications
https://refsnregs.waltjung.org/UnivReg_122714.pdf
This document describes a Universal Shunt Voltage Regulator , as optimized for positive and negative audio power supply use. It includes a high performance current source, adjustable up to 100mA of current. In a given application, a common form of shunt voltage regulator circuit is used for both POSitive and NEGative outputs.

Another way of looking at the shunt and series regulator is that the series regulator is effectively a cascode circuit without a load resistor. While the series regulator fixes the B+ voltage the audio circuit sees, the regulator also passes along all the current-flow variation to the unregulated portion of the power supply.

More Shunt Regulators The shunt regulator stands out due to its relative rarity. If it were the primary regulator topology, I would be writing about the series regulator instead. The contrast between the two is interesting. The series regulator operates in current phase with the load. If the audio circuit draws more current, the regulator sees ...

Some regulators have an output stage very similar to that of a power amplifier. These regulators have active devices that can both supply current (series regulator) AND sink current (shunt regulator). The simplest form of this is an opamp that has the output connected to the – input and the + input connected to a reference voltage.

This shunt regulator circuit's output is a MOSFET source follower operating at about 100mA. Its output resistance is (1/gm) and, at 100 mA of drain current, gm is about 1 siemens. The open loop output impedance is therefore about 1 ohm. If closed loop output impedance must be 5 milliohms or less, the required gain is 200X or more.

I am not sure if both of those regulators are of the same type, could be that the difference is series verso shunt regulator? John Walton's article in Linear Audio carefully states exactly which regulators he is testing, see Figure 1 below. Pooge 5.51 was published in issue #1_1995 of The...

T-reg: A High-Voltage Regulator for Tube Amps. November 1 2017, 10:00. Tube amplifiers can benefit from regulated and stabilized power supplies, especially sensitive preamplifier stages, but also (single-ended) power amps. But traditional high-voltage regulators add several extra tubes, complexity, and power losses, while good performance is ...

The 2008 article was probably the first time I saw Erno's shunt regulator. I bought many kits from Erno, but then he stopped selling. Jim's Audio on eBay sells a similar shunt regulator board. He gives a parts list if you buy it, I think all the resistors are same as Erno's, but he has a few semiconductor substitutions.
