For Sale: Audio Detail NV-06 Nuvistor Phono Stage
In reasonable condition and working order - this was originally an ex-demo unit that Mark Mainwaring (the designer and builder) used at shows *and as such the volume control and power switch on the phono stage have been disconnected (don't worry there is also a power switch on the linear power supply - in fact it is removed on current versions). This one is also unusual as it caters for both MC and MM inputs (MC input has inbuilt SUTs).
Reason for sale: my system has moved away from valves/tubes and so this is just sat on a shelf.
In view of this it is priced at £450.00 including postage to UK destinations. (I will not post this item overseas)
Payable by Paypal friends and family or bank transfer.
It is a 6 Nuvistor design aimed at the user who loves the valve phono stage sound, but wishes for something slightly different, compact and offering a lower noise threshold, but with a fast and lively sound. Built by hand in Great Malvern, UK, *the NV06 is all point to point wiring with the components mounted on a plated copper substrate.
We use paper in oil(PIO) and silver mica capacitors in the 2 stage passive filters.. With high quality German Audyn capacitors in the output.
What is a Nuvistor? *Nuvistors were designed in the late 1950's with the aim of combating *the rise of transistors within electronics..They are particularly good at VHF frequencies and are as small as possible(smaller than a thimble).. This means they are a lower noise valve, running at a lower voltage with lower internal capacitance than conventional valves.. This all results in a clean and detailed sound, therefore extracting so much more from your vinyl!
Every NV-06 has an external linear power supply, connected by over a metre of *cable to minimise any potential PSU hum and magnetic affects..
Specifications:
Inputs:
Moving Magnet 2.0-5.0 mV into 47K and 200 pf( can be specified at the time of order to suit your cartridge),
Moving coil: *0.2-0.5 mV into 100 Ohms
Output: nominal 500mV into 50K at full gain.
Power consumption approximately 12 watts
Mains input: 230VAC on IEC connector
Dimensions: W19cm x L15cm x H8cm
