Pro-Ject Tube Box S Phono Preamp. Bought it as a backup when I sent in my Musical Fidelity MX-VYNL for repairs. Had it in my secondary system for a month or two while the VYNL labored its way through the repair process (which ended up just being a faulty wallwart). Anyway, it was a fortuitous venture as I had forgotten just how much I enjoyed a tube phono stage when I was younger. In fact I went back to a tube phono stage pretty much immediately in my primary system and have been happily rolling ever since. Anyway, very low hours on the tubes, dead silent, and an inexpensive way to get introduced (or perhaps re-introduced!) to the magic that tubes work on vinyl. Thanks for looking!

Project Tube Box S2 Tube MM/MC Phono PreampPreamp is lightly used, in excellent working & cosmetic condition. Color is black. Very nice phono stage. Gain selection & loading options are easy to set & change. Supports MC/MM cartridges. Subsonic filter is great when needed. Preamp, AC Power, Manual, ship securely inside original retail packaging.Shipping is via 2-day Fed Ex insured Info below from Project: Description Tube Box S2 uses fully discrete circuitry – no operational amplifiers here (aka Op-Amps, used in simpler, more affordable designs but with some sacrifice to sound quality). It’s a hybrid design utilizing tubes in the input & gain stages. The standard, user-replaceable tubes sound stellar out of the box, though the design opens the gates for sound-shaping via tube rolling should you want to take it a step further. Tube Box S2’s sonic presentation is full & relaxed with a blossoming midrange more typical of much more expensive designs. The stage welcomes most MM & MC cartridges on the market with a wide range of gain, loading & capacitance settings. The S2 series’ 2-layer aluminum/steel enclosure shields the circuitry from vibration and electromagnetic interference for more music, less noise.Additional informationWeight0.41 kgDimensions13.1 × 10.3 × 7.3 cm FeaturesSuitable for MM and MC cartridgesPrecise RIAA equalization 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 aluminum/metal casing protects from vibrations and electromagnetic interferenceAvailable in silver or blackHandmade in EuropeSpecsTubes: 2 x ECC83 (12AX 7A)Input impedance: 10ohms, 100ohms, 1kohm, 2kohms A,Input capacitance/impedance: 47pF, 147pF, 267pF, 367pF,487pF and 587pF*/47kohms BInput gain: 40dB,43dB B ; 50dB, 53dB and 60dB, 63dB ANoise floor: 80dB (A weighted) at 40dB input gain 75dB (A weighted) at 50 dB and 63dB input gainTHD: <0,02% at 40dB input gain <0,05% at 50dB and 63dB input gainRIAA-equalisation curve accuracy: 20Hz – 20kHz / max. 0,4dBSubsonic filter: at 20Hz with 18dB/octaveInput: 1 pair RCA/phono socketsLine-level output: 1 pair RCA/phono socketsOutboard power supply: 18V/1.000mA DC, suitable for your country’s mains supplyPower consumption: 470mA DC, <1W in standby A: typical for low output MC cartridges, B: typical for MM cartridges or high output MC *Input capacitance is irrelevant for low output MC cartridges.
