This results not only in fantastic low noise phono amplification with clean measurements and accurate RIAA equalization, but also ensures a long product life-cycle as maintenance, service and repair are ensured for years and years to come. It also comes with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to his preference. Tube Box E will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high-end tube phono preamplifier.\" - Pro-Ject\u003c\/p\u003e\n\u003ch4\u003e🔎TECH SPECS\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003etubes: 2 x ECC83 (12AX7A)\u003c\/li\u003e\n\u003cli\u003einput impedance: 10 ohms, 100 ohms, 1 kohm, 2 kohms\u003c\/li\u003e\n\u003cli\u003einput gain: 40 dB, 43 dB \/ 50 dB, 60 dB und 63 dB\u003c\/li\u003e\n\u003cli\u003enoise floor: 77 dB (A weighted) at 40 dB input gain, 65dB (A weighted) at 50 dB and 63 dB input gain\u003c\/li\u003e\n\u003cli\u003eTHD: \u0026lt;0.02% at 40 dB input gain \u0026lt;0.07% at 50 dB and 63 dB input gain\u003c\/li\u003e\n\u003cli\u003eRIAA EQ Curve Accuracy: +\/- 0.5 dB\/20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003eSubsonic filter: at 20 Hz with 18 dB\/octave\u003c\/li\u003e\n\u003cli\u003einput\/output: RCA pair\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: 18 V \/ 1.000 mA DC\u003c\/li\u003e\n\u003cli\u003eDimensions (WHD): 4.1 x 2.8 x 5.1 in. \/ 103 x 73 x 131 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 0.99 lbs \/ 450 g (without psu)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e📦COMES WITH\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2x ECC83 tubes (replaceable)\u003c\/li\u003e\n\u003cli\u003epower supply\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pro-Ject","offers":[{"title":"Tube Box","offer_id":42849355333722,"sku":"eq-1954-black","price":349.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0105\/4542\/files\/pro-ject-tube-box-e-phono-pre-amp-black.jpg?v=1771262152","url":"https:\/\/www.turntablelab.mom\/products\/pro-ject-tube-box-e-phono-pre-amp-black","provider":"turntablelab.mom","version":"1.0","type":"link"}
