The simplistic Salas low voltage shunt regulator vs. LD1085/LM317

dvb-projekt · 24th December 2009, 06:23 AM

Hi to all,

i would like to open this new thread, to discuss and list all pros. and conts. from Salas low voltage shunt regulator schematics to normal low voltage regulators, like the LM1085 or LT317.

I could imagine there are many members out there, who are not able to read these facts "between the lines" in the specific threads.

You are kidding. It is a night and day difference. I built many times the LM317/337/LT1085, etc for over two years. The Salas shunt reg killed them all.

How so?
By what kind of margin?
Objectively or subjectively?

My experience with the simplistic Salas regulator was outstanding. Before it I tried the usual three legged wonders, then built the Sulzer, Jung SR, and others. They seemed to add something unwanted to the sound. The simplistic Salas regulator just sounded right. It's so simple and cheap that there's no point in not trying it and seeing what it does for yourself. IMHO it is the best value of all regulators that I know of.

Could you shortly explain the differences between salas latest circuit and yours?

Hi!
I think design is very very simple! The sound is the best, There are alot of transitor is not good!
I so shunt regulator is the sample One or many Hight Cap!
thank!

I don't know what you mean, it's pretty obvious, no? There are similarities because I started with his simplistic and modified it, but there are technical differences as well. I've been using his simplistic until recently. I haven't built his latest yet, been too busy with my project.

Hi!
I want to say is: design application Author, less components, the influence of the components will be less. Because it will sound better! I think so
Now, What do you think about it??!
Thank!

quanghao, I'm trying to understand what you're saying. Are you saying that the Salas circuit has fewer components and therefore it will sound better?

Yes! I try to do in simplistic Salas Hight voltage Use 2 BC560.
But in the new design change 2 Bc560 by one 2sK170.*

I show, the new design is beter than it!
