The CM7-GT (Glass Tube) uses a NOS Telefunken glass tube, which replaced the VF14/EF14 in 1960-1979. The CM7-GT has 9 patterns selectable from the PSU. The CM7-GT Circuit is basically the same as the CM7 with extra circuitry added to achieve the remote pattern changing. The CM7-GT use a PCB. The critical high impedance parts are assembled point to point. It also uses the same custom wound "large style" Neumann U47 transformer that we use in the CM7. The CM7-GT uses the identical grille setup as the original U47 and the CM7.
The CM7-GT comes standard with the K47 capsule which is identical to the original K47 used in the later versions of the original U47 (1959-1964). The M7 capsule can be special ordered. The connector at the bottom a 3/4 size Tuchel connector used on the U67/M269.
Package includes: The CM7-GT microphone system comes complete with a NOS Vintage Telefunken glass tube, a new K47 dual membrane capsule, a historically accurate "large style" BV8 transformer, power supply made in the U.S.A., tube mic cable cable, wooden microphone box, and 1-year warranty.
"All Wunder Audio Microphones are hand made in the U.S. because we want to keep the quality of the metal work on same level as the early microphones, this is not achievable with modern CNC machinery, widely used in China. Capsules, grille heads, rails, fine sanding surface on bodies, welding of capsule holders and baskets are purely a hand made process".
