Quad 2905 logo
« on: 15 May 2018, 08:25 am »
Dont suppose anyone knows how to check / replace the neon bulb in the Quad logo on a pair of 2905s ?
Speaker works perfectly but cannot turn on or change the brightness of the logo.
Can the badge be removed from the front ? Is it safe to do so ? Or does the speaker have to be partially dismantled ?
Thanks

You do need to remove the wood top trim. Then remove the metal side trims.  After that remove the front steel perforated grille by unscrewing about 16 small metal screws.  A small PC board can be found attach to the back of the front grille.  Wire cable to the PC board may have come loose.

Thanks Molar33
Eeek, so complicated for a loose wire or bulb.
I’ll take a look - is it obvious how the trims are removed and is doing all this in danger of mucking up the grille cloth ? Guess I had better let them discharge overnight too.

 Velcro like strips are use to attach grille cloth so you should be okay.  Take your time removing the black sheet metal screws.  They can easily strip and are pain to remove.  Also careful not to damage the dust cover while removing the grille.

But how do you remove the top trim and side bars ? Must admit I am getting cold feet about doing this. Perhaps I should just leave it until the time the Quads may need a service.
