You can’t see it from the outside. The specifications aren’t mentioned either.
A acquaintance ordered this one some time ago. The needed voltages were way too low.
I have the correct transformer(s) for less..I think that it will not disintegrate as the old version did. But the new type of foam isn’t perfect either. From around 2003 (where the newer version was used) and upwards I also see and experience that the new foam affect circuitboards. More noticeable in BL4000’s for instance.
Correct.
I strip the BL8000’s always completely. To the bare tube.
The foam tape isn’t part of the foam-kit. There are 2 different types used. A 6mm and a 19mm wide foam-tape.
I use the original foam-tape used by B&O to keep the BL8000 as original as possible.The circuitboard provides different settings for different voltages. It’s logically be (re)placing some SMD jumpers(s).
I would advise to let it be done by someone with electronic skills.Have you tried to enter the BIOS and look whether the harddrive is chosen as first bootable drive? It might be the CMOS backup battery which fails and therefore settings are lost.
The newer version of foam has been improved compared with to the previous one. The foam sits tight around the bass pipe to prevent audible resonance at lower frequencies.
The V-shape sits on top of the other parts and provides a “chamber” for the drivers.Looking at the picture, it is for sure that the T2/standby/small audio transformer has been replaced. On ebay they sell the wrong version. But I would start by measuring the voltages after T2 and it’s rectifier circuit.
