What trafo values (VA, secondaries V) are you using for your NS10 clone psu. I may have missed something in all these many posts. Im trying start to collect parts for implement this preamp.

In advance thanks for comments and assistance

First of all, I didnt build the version in this thread yet. I did build the version in Russ's thread with the dual supply, in fact it is still doing great service in my working room Whatever we made in that thread (surely not a NS10) it sounds really good indeed
My guess is that a 50 VA, 22 volt trafo would be nice for the real clone. But I suggest that if you have something on hand you could try and use that. A 2x12V donut would propably do nicely, running the secondaries in series, or a 2x20-24V running them in parallel or one for each channel. Watch the heatsink on the regulator, if you are using a 24+ volt trafo though!

I have a question, and I am not sure this is the right place to ask it. Nonetheless since you guys are pretty reliable here goes:
Working on my NS10 (real thing ) I found that the supply consists of one (1) FT317! pretty surprising, but I am not the one to critisize anything, since it works pretty good!! The single FT317 feeds both channels. Here is my question (just in case you were in doubt ) Would it be an advantage to put in a new LM317 instead?? I have no idea if the 317 family improved over the years??

If you don't want major tweaks (and you sez that you don't) leave it as is......even if you change it,you will not hear or measure anything.

just replace what you already planned

Hello Steen,

Do you plan to build a NS10 clone to compare with your
real one? That should be interesting. (And given
your amazing speed in building things, you can probably
whip one up in a day. )

Cheers,
Dennis
