And all electrolytic capacitors, one pitfall could be that<br />some of them are bipolar (why not grab a kit).<br />Check also for cracked solder joints, especially at connectors and driver transistors.</p> <p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/226276.aspxThu, 10 Sep 2009 05:17:04 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:226276Premiumverum0https://archivedforum.beoworld.org:443/forums/thread/226276.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=42&PostID=226276<p>Hi all,</p> <p>My friend&#39;s beomaster 6000 suffers from the usual old age problem of getting too hot.</p> <p>I will replace and readjust the idle current trimmers for him, and I&#39;d like to ask, before I begin, a couple of questions just to be sure:</p> <p>-The idle current trimpots are R234 and R134 on page 5-1 of the service manual, right (called no-load current trimpots)? <img src="http://forum.beoworld.org/emoticons/16.gif" alt="Whistle" /></p> <p>-Anything else, besides capacitors, that should be replaced and readjusted while I&#39;m in there (the offset output amp trimpots perhaps, see also 5-1 of service manual)?</p> <p>-Are there any &#39;traps&#39; I might fall in to (what&#39;s the English sentence), things that can go wrong and make trouble even worse?</p> <p>Any advice, comments or good BM6000 stories are greatly appreciated!<img src="http://forum.beoworld.org/emoticons/05.gif" alt="Wink" /></p> <p><img src="http://forum.beoworld.org/emoticons/58.gif" alt="Laughing" /></p><div style="clear:both;"></div>
