Pretty well then. The soft RC to test goes on the other end of the regs, at the load's physical rail. Since with your better probe there seems to be very little to see on the scope if any, lets see if it can change something sonically or not. So what you reported above is after the new RC?

Sorry, not yet put in the RC at reg output. Will do that now and report back.

Sonically it is superb! Very happy so far...

Default C2 distance from PCB

Has anyone mounted capacitor C2 off of the SSHV2 PCB? Any issues? How far is it OK to mount from the PCB ?

I would be a bit concerned as it's across the sense lines...so just checking!

That's a beauty!! Great work. Ya know, guys like us will pay for this kind of build quality (oops, did I just say that?)

Don't do that. Its there to filter the Vref noise. With cabling, inductance and EMI are going to mix.

As I thought. I've seen some do it, but given the point in the circuit where the cap is, I can see that could be problematic.

Thanks Salas.

Hi

For my burfday I wish me a split SSHV2.5 for smaller preamp stuff. One CSS module eating the 20 mA extra current and 2 output/Vref sections, one for each channel.

Purpouse would be optimum channel separation without having to burn an extra 20 mA per channel for applications that might only take 10 for them selves. That would make need for smaller trafos, lesser EMC etc.

Do you think it would be fruitful for me to experiment? Is it possible to split to 2 mosfet/Vref sections after CSS?

best
Staffan

Default New installation

I have just installed a couple of SSHV2 regulators in my RTP3. These replaced the Emile Sprenger HPHV shunt regs, which I have had persistent problems with over the years.

Initial signs are very positive - I will post an update and photos in due course!

Many thanks for your efforts, Nick!

Alex
