Hi TM Black.
I have used my very, very crummy version of the Threshold NS-10 circuit continuously since I built it ages ago - eek in 2006!
I put in some different jfets as mentioned very early in this thread. All up my very, very crummy version of the pre-amp cost me $AUD90 to build including the case and transformer. I did it no favours at all: I had just finished my LM3886 chipamps and discovered I didn't have a pre-amp, so went to my local Dick Smith Electronics and bought el cheapo, boggo standardo components, burnt a PCB, made my first ever chip-regulated power supply and plugged it in and it worked ... once I got the orientation of the transistor right. (What a dummy).

I will change one day to a very, very crummy version one of Nelson's balanced pre-amp circuits, but I have no time and little need at present. Meaning, I still enjoy this little pre-amp for my listening.

Regards from George.
And again, many thanks to Nelson Pass for allowing us to use (and abuse) his old circuits.
