Vacuvox V41 Stereo/Dual-Mono Tube Microphone Preamp - Steel Tubes

The Vacuvox V41 stereo/dual-mono microphone preamp is a recreation of the ultra-rare Maihak (Telefunken) V41, widely considered to be the Holy Grail of preamps! The steel tube option available here uses NOS Telefunken EF12 steel tubes like the original.

The 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 (<-90 dB). It is also more stable which results in a tighter bass end.

The 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.

The 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.
