* Copper lined mounting panel * Input impedance 100k ohms
* Output impedance 800 ohms
* Gain 13dB.




Bill,

Looking at the production unit it says that the output impedance is 180ohms?  Is the 800ohms for the pre-production one correct or just a typo?  Also, on the gain which says 13 v/s 17.

Hi Deepak.
 All production unit Purity Series preamps utilize transformer coupling outputs which gives us the 180 ohm output impedance. This particular unit does not have balanced outputs therefore does not use any output tranformers which gives us the 800 ohm output impedance.

 This piece is also set for 13dB of gain.

 Hi Chris,
 yes, I did take it he was serious about a new preamp. I, however, was not serious about the "step up" comment as could be seen with the laughing rolly thingy.

Evan, you are mor ethan welcome to contact me if you would like more information on the Purity preamps. What features are you looking for or require?

If a more attractive price might help, send me an offer. I am only trying to offer non-production units at a good price to clear the racks and this is the last piece left.  The only downfall is that I am busy now with Purity Reference and Statement orders so it could be a while before I get pieces built for the showroom.

Oh - you're killing me!

Unfortunately, I'd doubt you'd let the unit go for what's in my pocket - gum, lottery ticket, pocket knife, comb missing teeth. Now if the ticket hits, then we can talk.

What kind of tubes?

I fear after listening to tubed preamps, my passive pre is not getting the job done for me.

The Nervosa has hit me hard and deep.

Gene,

The Purity One is based on 12au7 similar to the Bella you heard.
