“...a part of the reason why the original U47 is still sought-after is that it is almost uniquely difficult to reproduce today. The problem lies not with the M7 and K47 capsules used in different iterations of the U47, which are still manufactured by and .berlin , respectively. The issue, rather, is with the impedance converter, a metal-cased miniature pentode valve called the VF14 that was used well outside its intended design parameters in the U47’s preamp circuitry. The VF14 was only ever manufactured by one company, , in relatively small quantities, and only about
a third of the VF14s produced met Neumann’s standards for use in microphones. VF14 manufacture ceased in 1954, and by the early ’60s, Neumann themselves were having such difficulty obtaining usable examples that they were forced to discontinue the U47 and its sibling the U48.”
