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.

Biete diesen Phono Preamp mit Röhrentechnik von Pro Ject an. Ich wollte den Phono Bereich mit der True Balance Technik von Pro Ject bestücken, habe mich jetzt komplett unentschieden. Ich habe die Tube Box DS3 B als retour vom autorisierten Händler erworben am 11.06.2024 und war bei mir nicht einmal in Betrieb. Die Einstellung besonders für MC Systeme, sind super, deshalb hatte ich ihn auch gekauft. Der Klang soll in dieser Preisklasse außergewöhnlich sein. Bitte alle technischen Details auf der Pro Ject oder ATR Website erlesen.

Ich biete den Phono Verstärker in schwarz und in sehr gutem Zustand an. Das Gerät kann wahlweise für MM oder MC Tonabnehmer konfiguriert werden. Kapazität und Widerstand sind über DIP Schalter am Boden einstellbar. Abholung sehr gerne. Versand in OVP per DHL möglich. Privatverkauf - keine Gewährleistung oder Rücknahme.
