Just how close can the source be brought to the power amplifier? VERY CLOSE! Less in the middle means better sound. Our circuit does not look like a metropolitan road map. Going from Point A ----> B as directly as possible, as accurately as possible is Niteshade's design policy, no matter what it is we develop.

how 'bout a remote volume control option ?

[Niteshade]

There were no remote volume controls in the 1950's unless there was a cord attached it.  aa

OK- Enough with the snide remarks from me. Several people have asked for that option and it may come about sometime. There's something unique and interesting about mixing two totally different technologies together that is alluring.

Hi Blair:

I guess there is just 1 input and how many outputs in the back?

A nice "rear" shot will turn a few heads. 

BTW, what sort of volume control does it use?  A pot, or something else? 

How much gain is there?

Gain is 25+db and it uses a carbon track pot (the only kind I like).

There are two input sets and one output set on the back.

Thanks for the good questions!

2 inputs
1 output

If there are any questions regarding our new preamplifier. please ask! 

[Niteshade]

I know there's a gorgeous red NS-3 out there- but don't forget about this beauty! Just like all the rest of our products- you get to choose the color if it isn't already built.

Did you know that our tube preamplifier works flawlessly with solid state amplifiers? Triode preamplification in tandem with a high quality solid state amp provides impeccable delivery performance. 

Naturally, our preamp works like a dream with tube amplifiers. Try a NS-6N7 with our preamp for a 100% triode dream system. 

[Niteshade]

All the virtues of triode preamplification wrapped up in a point to point wired steel bundle of joy.


It is indeed possible to have longevity AND performance at the same time, in the same package.

Hi Blair,

Ok, tell me more about this carbon track pot. What is the ohmage of this pot? What makes this so good?

So what is the output impedance of the preamp? Is this inverting or non-inverting? Is it cap coupled at the output? Just curious why the different tube types? I always like to know what the engineer is thinking.

The volume control is a 100K linear taper pot made by Alpha. I always use carbon track pots because they are reliable and sound good. Most of your 1950's & 60's audio equipment use them. If one of these ever gets scratchy, all it needs is a spray of contact cleaner. If it even needs to be replaced, they're easy to find. I think people will find that audio equipment based on non-proprietary components is a better value in the long run.

Thanks for the info on the volume pot. Linear taper hmmm, Do both pots track better than the audio taper?

Hello Ray,

I forgot to answer your other questions:

The volume pot tracks very well and provides excellent volume 'selection'. What I mean is, it's easy to dial in the exact volume you want. There are no rapid jumps, the volume doesn't become too loud with just a 1/4 turn as is the case with some equipment.

Output impedance is 10K and it is non-inverting. The output is capacitor coupled. I can build this amp with either 12AU7's or 6SN7's. This is a customer's choice and doesn't effect the overall design much.

More tubes can be added in parallel for a lower output impedance.

Hi,

10K output Impedance, that would seem a bit high for SS amps. Mine has a sort of matching impedance setup to match theoutput impedance of a preamp to the amplifier. Now, before you say that's not correct, I do understand that. However my amplifier will work best with anything in the 800 Ohm or under.

On your volume pot, why did you choose 100K versus 50K? I applaud the use of the Linear taper pot. Never thought of that idea. I understand the Alpha Audio tapered stereo pots don't match up especially in the lower ranges.

Most amps I am aware of have an input impedance of 50K to 200K on average. You said yours is variable?

I like the 100K's range. It seems to work the best.

Hi,

My SS amp will have when I am through with the final mod, a way to match up preamps if the output impedance of that amp is 800 ohms or below. I've seen tube preamps with a 560 ohm output, a 300 ohm output, 600 ohm output. Those are just three that come to mind.

I was asking about the pot, because I had seen the use of 50K pots. That was why I had asked why you are using a 100K pot. Not any sort of criticism or anything like that, just more out of curiousity than anything else.

10k output, 25dB gain... non-inverting... one tube per channel... interesting   Is this a cathode-coupled circuit?

If it were Cathode coupled, I would think then the output impedance would be much lower. Maybe, the other tube is used for a CCS circuit. Just guessing.
