Nina is a tube tape head preamp using the venerable 6922/E88CC family triode and is designed for use with most reel to reel tape decks, consumer or pro.

The preamp circuit is a ground up design by our partner the renowned tube circuit guru Ray Waters. His brilliant circuit has been mated with our in-house designed regulated solid state power supply. This is not a re hash of a phono preamp circuit!

The result is a fantastic sounding tape head preamp that is able to work with a wide range of playback head impedances. Another unique feature of this design is that Nina can be switched between NAB (7.5 & 15 IPS), IEC 7.5IPS and IEC 15IPS. Or, Nina can be built for IEC only, 7.5, 15 & 30IPS, NO NAB.

The standard version uses unbalanced RCA in and outputs.
As an option, Nina can also be built with a Balanced XLR in and outputs using the superb Lundahl LL1544A audio transformers. This version will have no RCA sockets.
An all black anodized chassis is also available.

An important note about Nina.
Nina is a very high gain preamp, 50dB, using tubes. It is inevitable, that some tube hiss will be audible at very high volume settings, by that we mean volume settings which are above normal listening levels. We take time to match the tubes as well as using low noise tubes to keep that tube hiss to a minimum.

Nina is built to order and will take around 4 weeks to complete and ship.

If you wish to return the unit, a 15% restocking fee will apply and the shipping cost for this will be on your account. The time limit is 1 month  from date of shipping for returns. For more details, please see our terms and conditions.

Nina is a tape head preamp, so it must be connected directly to the decks playback head, NOT the tape deck audio output!

Nina is housed in a custom anodized aluminum 2U rack mounting chassis .


Tube options:

A pair of matched NOS 6DJ8's or the excellent Russian made 6N23P-EV's.

Thus is our new generation Nina tape head preamp coming soon. We have made some upgrades to the preamp circuit and power supply, but most important, we have added a pair of fully calibrated VU meters.
The VU meters will be calibrated to +3dB @ 0dB VU as standard, but can also be calibrated to +6dB @ 0dB VU.
We hope to have our updated version of Nina ready for production in early January, so stay tuned!
