The steel tube option available here uses NOS Telefunken EF12 steel tubes like the original.\u003c\/p\u003e\r\n\u003cp\u003eThe Vacuvox V41 preamp performs exactly like the original in sound, frequency and phase behavior. It features an upgraded regulated power supply with a much lower noise floor than the original (\u0026lt;-90 dB). It is also more stable which results in a tighter bass end.\u003c\/p\u003e\r\n\u003cp\u003eThe Vacucox V41 has 5 dB more gain than the original by using the output transformer in a different way. This recreation also features a -20 dB pad, phase reverse, +48V phantom power, high-pass filter above 60 Hz, and an extra linear potentiometer to adjust the gain in between the 5 dB steps. Channels can be matched by an internal trimmer.\u003c\/p\u003e\r\n\u003cp\u003eThe V41 has two channels each with separate power supplies. Each channel has 6 transformers and 4 tubes. This version uses 1x EF12K, 2x EF12, and 1x EZ11 NOS tubes like the original Maihak V41. The transformers are custom-wound at the same factory used for the U23. Audio transformers are perfect replicas from the original Malotki made from the purest permalloy (80% nickel). Input and output transformers are shielded through numeral cans and the power transformer has a static shield to prevent noise and clicks coming in from the outside.\u003c\/p\u003e","brand":"Vacuvox","offers":[{"title":"Default Title","offer_id":44451117793383,"sku":"212067","price":13995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/vacuvox-v41_212067_1.jpg?v=1787095906","url":"https:\/\/vintageking.com\/products\/vacuvox-v41-stereo-dual-mono-tube-microphone-preamp-steel-tubes","provider":"Vintage King","version":"1.0","type":"link"}
