After about 2 years in the making, we have finally released our model Nina, tube tape head preamp.
This really is an excellent sounding tube tape head preamp, and a real and viable alternative to your reel to reel decks OEM playback preamp.
I will not go into a lot of details here, please visit...
hey all,
just released our latest addition to our lineup, model Billie, our entry level Tube Phono Preamp, for MM cartridges only.
I won't go into much detail here, go to our web site www.tubenirvana.net and click on Billie.
Price for this amazing sounding phono preamp is $489.00 plus...
Anybody really. I always liked EQ's, had them in my systems most of the time in the early days. Started to build it just for fun, decided to add it to my lineup.
I guess I came up with it for myself first, kind of a pet project :-)
Graphic EQ of 5 tubes per channel for frequency adjustment, one frequency per one triode part, so two frequencies per tube, one tube as a differential pair and half of one as a cathode follower.
Frequencies will be 32Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1KHz, 2KHz, 4KHz, 8KHz, & 16KHz.
The unit will...
its not for the purist.....thats for sure. Bench tests have worked amazingly well, it is basically an op amp circuit using tubes, a very simple but very effective circuit. It will be a challenge keeping it quiet with minimal hum etc., a total of 13 tubes!
but here's something out of the left corner...and don't tell anyone....;) I am working on a stereo 10 octave/CH all tube EQ...model Hendrix......I think its going to be quite unique, I've not recently seen any tube EQ's for home audio use. It will have RCA and XLR in & outputs...but like I...
I had looked at 300B's, but for now I will not. I've not even got requests for perhaps building a 300B amp.
Not sure why, but the 300B does not really 'turn me on'.....;)
No, KT88 is the 'biggest' tube that can be used. You can however use 6550 or KT90, all that needs to be done is to re adjust the 'balance'/bias. Especially the 6550, there some really great sounding NOS samples out there!
If you've got your heart set on KT120's, it would need to be my model...
thanks Andre for posting some of my gear here.
I will give forum members a good deal on prices. My margins are not very high, but I'm sure we can come up with a good forum member price!
This not only applies to the models shown here, but on all my models!
