They better ask me before proceeding to something final, because there are details and options.

I mind the BC550 are fryed because the reg. only gives 60VDC & can't lower the voltage so I will change Q3 for BC546B and the resitors R2, R3, R5, trimmer R6 & R8 & I will let you know.😡

It's a looong way.
This will be - for me - the 3rd or 4th version of a PCB (I'm a toner-transfer guy) based on your schematics, all working flawless.
But that's another story, the v1.2 (as correctly Massimo pointed out, as per post 1893) need a more attentive job, not only a matter of not crossing lines as I previously did. Anyway, thank you in advance for your kind offer (and for sharing your fantastic job!)

Hi Salas, lauret,
Would you have any more info/ link to where this "D1 + Salas Shunt Reg" can be found, please?

Hi All
Is a long and fantastic good thread. I have been browsing at the attachments
Please tell me how to set the CCS with leds and with transistors.
200mA is to much for my need
This my first post in this thread
Thanks to all

Changed all components for Rs, leds lit, voltage is 58 VDC but can't decrease the voltage with the trimpot, mosfets are cold, I'm afraid that are frieds, any other idea to solve the problem?

Thanks Salas, solved the Rs problem, now the reg. is going on perfectly, a photo just for fun:

An externally hosted image should be here but it was not working when we last tested it.
Read a bit from the start. Its been explained many times. Rule of thumb for the 3 leds ccs schematics I=2.2V/Rset very roughly.
Rs first impressions
Wow, really it's a great step forward the Rs setup, it's like you drive a formula 1 car, all is plenty of extra power, fast, dynamic, very, very clean.
I really recommend fo everybody to do the up-grade to Remote Sense, it's easy to do & you get a lot of more "good sound" than the work done.🙂
Congratulations Salas & thanks again to share & help us.

Nothing much. Getting nearer to no cable. Thank Lord Kelvin. I am only trying to be useful. Enjoy DIY.
With all DIY things, I am more that enjoy, now I am living in other dimension, will be the "unknown diyaudio dimension"😀????
