Equipment Support (misc.)

NB: Price is for a set of 4.

Note on choosing the correct 4TUBE feet for your valve amplifier:

Owing to the unusual weight distribution of valve amplifiers with the heavy Transformers typically at the rear, the feet have a rated loading of:

  • 20kg at the front and 35kg at the rear for the "Up to 22kg Loading"
  • 35kg at the front and 55kg at the rear for the "Up to 50kg Loading".

Manufacturer's Description

The heavy duty, high voltage transformers of Tube Amplifiers produce mechanical vibrations which disturb the flow of signals within the internal boards, cables, electronic components and especially the sensitive tubes. An additional "floating" aluminum inlay called "HS-plugin" is used for horizontal stabilisation.

bFly's 4TUBE absorbers demonstrably make the sound more relaxed, spacial and natural.

The 4TUBE absorbers are specifically designed for Tube Amplifiers and now are also available with screw threads in a set of 4. If the screw option is selected the four feet come shipped with two sets of 4 x M8 screws of lengths 25 and 35mm. Ideally you should just rest the equipment on them to take full advantage of the cork absorption.

Possible configurations:
With the cork side under the feet of the device
Positioned directly under the equipment base
Existing Feet replaced with the screwable version

Foot Dimensions: Height 21mm Diameter 44mm
