Stajo will advise you on that, who has a stash of chokes to check out. Me I said use a cmult cascade at the output.
My "cmult cascade" is still intact.
I just added toroid primary as a choke. I can leave it there, but I need to install it at Raw DC box. My pre-amp box has no space for it.
However, I'm sure right value choke can remove all my AC junk coming from Raw DC.
What you mean, you added a second cmult in series and you still get variation in hiss by playing at the raw end? Then its an EMI thing mainly.
No. Please see attached picture.

I wanted to ask, is there an optimal temperature that the fets should work in?
I do not expect you to give me a specific Celsius value. But I am currently using a big heatsink for one of my BiBs and it is running pretty much cold. Should I allow the fets to heat up a bit ?
Thanks again

You mention that this thing makes 108dB kill @ 100HZ. I'm in US and I probably have to deal with 120Hz (not 100Hz).
One cell you already got, just add the end part. At 120Hz it does even more. It basically flats out 10-20dB even better towards the highs.

In electronics the cooler the better if its not a matter of needing extra power. In case of a bib, extra power can go towards lower self output impedance, so why not take some advantage of the spare cooling and rev it up a bit.

Like this?

Yeah it was in the back of my head to try something like that... I just need to get a bigger trafo. Big smile
We don t need no water let the freaking thing burn
Yes, easy. You will need 13.2V output from the 317 for the two vbe losses now. I would stick the second cell right on the BHL receive points to avoid that EMI we suspect finding cables to creep in again.
Got it. I'll try and report back.

OK
It works. Very quite now. Please see final setup.
Thank you Salas.
