That is a difference that matters with tubes that are no longer manufactured.\u003c\/p\u003e\n\u003ch3\u003eSame transformers, same tone as the module version\u003c\/h3\u003e\n\u003cp\u003eThe high-nickel CT-110HN input transformer and CT-41 output transformer are the same components that build the CA-70 module's character, so moving to the standalone version loses nothing in sound, only gains independence from the PS6 rack. A 42-54dB gain range and a flexible mic\/line pad cover most studio uses.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStandalone 2U enclosure with integrated power supply\u003c\/li\u003e\n\u003cli\u003eSlow-ramping power supply with linear regulation\u003c\/li\u003e\n\u003cli\u003eTwo-stage 6J7\/6C5 tube circuit on NOS tubes\u003c\/li\u003e\n\u003cli\u003e42-54dB of gain\u003c\/li\u003e\n\u003cli\u003eCT-110HN input transformer, CT-41 output transformer\u003c\/li\u003e\n\u003cli\u003eTone shaping via negative feedback with LOW filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFormat: standalone, 2U\u003c\/li\u003e\n\u003cli\u003eCircuit type: two-stage tube, 6J7\/6C5\u003c\/li\u003e\n\u003cli\u003eGain: 42-54dB\u003c\/li\u003e\n\u003cli\u003eMic input impedance: 150 ohm\u003c\/li\u003e\n\u003cli\u003eLine input impedance: 20k ohm\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 600 ohm\u003c\/li\u003e\n\u003cli\u003eTransformers: CT-110HN (input), CT-41 (output)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Coil Audio","offers":[{"title":"Default Title","offer_id":54961315643729,"sku":"61022","price":2399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/Coil_Audio_CA-70S_MK2_1.jpg?v=1789721742","url":"https:\/\/wrdtunes.com\/fr\/products\/coil-audio-ca-70s-mk2","provider":"Wired Tunes","version":"1.0","type":"link"}
