He sells the lamp kits for the BM 1900. As he will surely suggest, you might as well replace all of the lamps whilst you have the unit open. Trust me its a lot of work taking it apart and putting it back together again but worth it a 100%!! </p><p>&nbsp;Good Luck!!</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/74730.aspxSun, 30 Dec 2007 12:05:38 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:74730Jacob0https://archivedforum.beoworld.org:443/forums/thread/74730.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=74730<p>Am I right in thinking that the bass and treble should have red lights on the display? I have just been given a 1900 and if so these bulbs need replacing. Is it an easy job and where do I get them from/ how much?</p><p>Cheers</p><div style="clear:both;"></div>
