The low-frequency noise generated by a valve is most conveniently specified as an equivalent voltage on the control grid for a specific bandwidth. Collection JR Jacob Roschy.

The EF86 [1] is a high transconductance sharp cutoff pentode vacuum tube with Noval B9A base for fata applications. Unlike many pentodes it was designed specifically for audio applications, low noise and low microphony being claimed advantages, although a rubber-mounted vibration-resistant base was still recommended. Its design is low noise and anti-microphonic. The EF86 was used in many preamplifier designs during the last decades of vacuum tube hi-fi development.

From Wikipedia, the free encyclopedia. Care in the design of the valve to ensure that the wf86 structure and its mounting are as rigid as possible has reduced the microphony of the EF86 to a very low level.
