Pro-Ject Tube Box S2 Pure-Tube MM/MC Phono Preamplifier (Black). Gently used and ready for a new home. This little thing packs a big wallop!

Used once great condition comes with power cord

Upgraded Tubes: Lets face it... NOS 12AX7s are getting scarce. When that happens, the price goes up. The good news? The quality of current production 12AX7s is getting better and better. The latest Russian re-issue is a perfect example. These Gold Lion 12AX7 re-issues sound incredible: A full, glorious midrange with great texture and liquid detail, extended yet controlled highs, tight bass. I have A Project Tube Box S2 i am offering. The tubes are Kevins stash witch are the best matched available and I had them cryogenically treated $200.00 worth of tubes.Tube Box S2 is Pro-Jects very first product to feature discrete circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to their preference. Tube Box S2 will give a full and relaxed laid back sound with lush mids, just as expected from a much bigger high end tube phono pre-amplifier. It offers support for both MM and MC cartridges and comes with many gain settings to be switched on the front panel. Five variable input impedance settings are available to adjust to any MM cartridge, the 47 k ohms input impedance setting is fixed and suited for high output MC cartridges. The aluminium/metal casing is adapted to our DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound.A true high end solution in a much smaller package!FeaturesSuitable for MM and MC cartridgesPrecise RIAA equalisation in two parts, passive/activeFully discreet circuit design without OpAmps2x ECC83 tubes (replaceable)Front-sided Subsonic filter buttonFront-sided Gain controlUltra low noise circuitry with FET input stageDual mono circuitry for optimized channel separationPolystyrene capacitors used where possibleGold-plated RCA in- and outputsExternal power adaptor and multiple internal power suppliesWell-filtrated high-voltage anode power supplySandwich alu/metal casing protects from vibrations and electromagnetic interferenceAvailable in silver or blackSpecificationsTubes2 x ECC83 (12AX 7A)Input impedance10 ohms, 100 ohms, 1 k ohm, 2 k ohmInput capacitance/impedance47pF, 147pF, 267pF, 367 pF, 487 pF and 587 pF* / 47 kohms, Together with other input impedance settings without any influence!Input gain40 dB, 43 dB / 50 dB, 60 dB and 63 dBNoise floor80 dB (A weighted) at 40 dB input gain, 75dB (A weighted) at 50 dB and 63 dB input gainTHD<0.02% at 40 dB input gain <0.05% at 50 dB and 63 dB input gainRIAA-equalisation curve accuracymax. 0.4 dB/20 Hz - 20 kHzSubsonic filterat 20 Hz with 18 dB/octaveInput1 pair RCA-level output1 pair RCA/phono socketsOutboard power supply18 V / 1.000 mA DC, suitable for your countrys mains supplyPower consumption470 mA DC, <1W in standbyDimensions W x H x D with sockets103 x 73 x 131 mmWeight410 g without power supply Unit comes with original box {rip in bottom right corner} and wall wort.

Project Tube Box DS2 Phono Preamp. Moving Magnet or Moving Coil. lots of features. works great. comes with power supply. Description Our precision Tube Box DS2 phono preamplifier benefits from outstanding circuitry design by the brilliant Czech engineer, Dr. Bohumil Sykora. Compatible with most MM & MC cartridges on the market, it offers two turntable inputs so enthusiasts can easily toggle between two different turntable/cartridge combos. Continuously adjustable (‘on-the-fly’) input impedance for low output MC cartridges is a must-have feature that allows you to ‘tune’ the loading to achieve the sonics that best suit your system and your ears. Other features include input capacitance for MM cartridges and a switchable subsonic filter to stave off mechanical noise. All components including the tube output stage and polypropylene capacitors are audiophile-grade and guarantee a breathtaking sonic experience. Features Suitable for MM and MC cartridges Precise RIAA equalisation Ultra low noise circuitry Selection between 2 phono inputs & 2 line outputs Dual mono circuitry for optimized channel separation Selectable input impedance (for MC: fixed or variable) Selectable input capacitance (for MM) Selectable subsonic filter Gold-plated RCA in & outputs Sandwich alu/metal casing protects from vibrations and electromagnetic interference Finishes: silver or black, with/without wooden side panels Handmade in Europe Specs Tubes: 2 x ECC83 (12AX7A) Input impedance: variable 10-1000 ohms/ 47.000 ohms (47k?) Input capacitance : 47pF, 147pF, 267pF, 367pF Gain: 40, 45, 50, 60 and 65 dB (switchable) Output voltage typically: 500 mV/1kHz at 5mV/1kHz (at 40dB) Noise floor: 88 dB (A weighted, at 40dB gain) THD: <0,04 % RIAA-equalisation curve accuracy: 20 Hz – 20 kHz / +0,2dB / -0,2dB Input: 2 pairs RCA/phono sockets Line-level output: 2 pairs RCA/phono sockets

Kaufdatum beim Händler war der 17.10.2024, der Phono Preamp hat also noch fast die volle Gewährleistung und Garantie. Ich habe mich schlussendlich für einen komplett anderen Verstärker entschieden, weswegen ich ihn nun verkaufe. Er hat ca. 30 Betriebsstunden und ist quasi neuwertig und ohne sichtbare Gebrauchsspuren, Kratzer oder Ähnliches. Der Pro-Jet stammt aus einem Nichtraucherhaushalt und wurde selbstverständlich pfleglich behandelt. Ich finde, dass er ein ausgezeichnetes Preis-Leistungs-Verhältnis bietet und jeden Standard eingebauten Phonoeingang eines Vollverstärkers in der Preisklasse bis 2000 Euro um Welten übertrifft. Der Pro-Ject Tube Box S2 wird vollständig in der OVP inkl. Netzteil geliefert. Informationen zum Artikel: Innovative Röhren Phono-Vorstufe im Miniatur Format mit High End Sound!
