Regulators from Jims Audio.
 
Hi all, I want to use a shunt regulator for the input and VAS of a class A amplifier, with an output that can be adjusted between 30V and 35V. Has anyone any views on two regulators from Jims Audio, one is a Kubota type and one termed "class A shunt regulator". They both have variable posative and negative outputs in the voltage range I require, with ample current.
Buying a kit would be an easier solution for me than trying to make my own PCB.
Thanks for your help

I have a similar question about this shunt regulator PCB on ebay. It ships from Indonesia and is described as "overstock Shunt Regulator PCB design by Mr. Salas". Any comments would be really helpful...

It doesn't look anything like the pcb I bought from Salas at all.

It might work after all.

I was interested in this one Low impedance 500mA class A shunt regulator kit ! | eBay

Hi, I cannot find a circuit for the Kubota regulator, I presume it's a shunt type regulator, but I don't know for sure. Has anyone any details please? Here is a diagram of the second regulator I am interested in ( the class A shunt regulator ) does it look reasonable?
thanks for your help.

I don't believe that is a shunt regulator. It looks like a regular series regulator to me.
