Bermuda Audio Tuning Tube Dampers NEW


Durob Audio introduces under the brand name “Bermuda Audio Tuning” a series of new tube dampers for 19 – 22 mm tubes like 12ax and 12au7. The idea is simple: add mass to the tube through a more or less flexible connection made out of heat resistant silicon rings. Each ring is attached to the tube in a so-called “Bermuda-Triangle” configuration. The tube dampers are provided in different combinations:

2 aluminum rings / 1 silicon ring (minimum damping) € 15

Weight: 10,8 grams

Height: 11 mm

Outside Dia: 34,6 Dia



3 aluminium rings / 2 silicon rings (minimum – average damping) € 20

Weight: 16,9 gram

Height: 22 mm

Outside Dia: 34,6 Dia



4 aluminum rings / 3 silicon rings (average damping) € 25

6 aluminium rings / 5 silicon rings (maximum damping) € 35

Weight: 36,2 gram

Height: 40 mm

Outside Dia: 34,6 Dia

The “Bermuda” tube dampers come with 2 versions of the aluminium rings (with low weight variation between each) so you do the maximum fine tuning possible.

The “Bermuda Audio Tuning” tube dampers are available in 2 colors (silver and black) and suitable for all tubes with a diameter of 19 – 22 mm.
