Collection of Tomasz Szczesniak PL. In high gain applications such as tape recording care should be taken in siting the valve, particularly when a loudspeaker is present in the same cabinet or where a motor is mounted on the same chassis.
From Wikipedia, the free encyclopedia. You can help Wikipedia by expanding it. At higher frequencies the effect of vibration is usually negligible on account of the damping provided by the chassis and the valve holder.

Its design is low noise and anti-microphonic. Collection of Bruno Candreia CH. Daata rarely used EF83 is a remote-cutoff pentode  otherwise similar to the EF86; the remote cutoff variable mu makes it suitable for applications such as automatic gain control agc in tape recorders.

Erb Analysis by original leaflets. You will find thousands of tubes or valves with interesting links.
Antique radios, Old Time Radios. Although used datz circuits such as tape recorder input stages and instrument amplifiers, microphony can be a problem, even when mounted in a vibration-reducing valve holder.
Collection of Dennis Jaroschek D. The UF86 is identical with the exception of a Collection of Klemens Rhode D.
This can be further reduced by centre tapping the heater to earth. Collection of Jacky Parmentier F.
The landmark amplifier designs from Mullard’s application laboratories all specified the EF86, and today it is still the valve of choice for this work. The EF86 is the standard early stage audio pre-amplifier valve.
An industrial variant of the tube is known as You reach this tube or valve page from a search after clicking the “tubes” tab or by clicking a tube on a radio model page. Collection of Ralf Meinke D. RTT Franzis Care in the design of the valve to ensure that the electrode structure and its mounting are as rigid as possible has reduced the microphony of the EF86 to a very low level.
Warning the PDF file is 3. The full Mullard data sheet is available by clicking the valve name at the top of the page.

The EF86 was used in many preamplifier designs during the last decades of vacuum tube hi-fi development. You even can look up radio models with a certain tube line up. Type EF86 was first introduced in
