Description
New anti-vibration rubber suspension parts for the transformer/power supply in the following Bang & Olufsen models:
Beolab Penta
Beolab 3000
Beolab 4500
Beolab 5000 (Type 6706 powered speakers)
In the above mentioned amplifiers and powered speakers, the transformers/filter capacitor block is held by four screws with each two rubber bushings, one bushing on top of the transformer block and one below for each screw.
The original fastener bushings are known to dry out, harden and become brittle. As such they will no longer isolate vibrations
from the transformers, which will transfer to the amplifier chassis and cabinet.
This often causes the amplifier to produce an annoying humming sound, audible directly from the amplifier or speaker cabinet, and in severe cases, it can be observed even in standby mode.
These are direct replacements for original Bang & Olufsen part# 2938154
One set contains 16 pcs. as shown, to cover a pair of amplifiers.
Note: When mounting it’s adviseable to add a little Locktite or similar thread-locking product to the outer 4-5mm of the screws threaded ends.
It is also adviseable to tighten the screws only until deformation of the rubber bushings is observed.
