Furthermore it&#39;s shielded in a metal housing that will, at least to some extent, place an electromagnetic load on it so it will get a bit warm even if running alone. In your case I wouldn&#39;t worry. </p><p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/11493.aspxWed, 09 May 2007 06:48:44 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:11493canivet2904680https://archivedforum.beoworld.org:443/forums/thread/11493.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=11493<p>My farther once owned the 1001 model and had the same problen you discribed. the intense heat even came though to the top panel. However mine tends to only get&nbsp;extreamly hot at&nbsp;the rear botton right hand side of the unit.</p><p>The main underside and&nbsp;and vents holes at the front side&nbsp;are not effected but are only slighly warm to the hand after an hours use.</p><p>Taking into account what you&nbsp;told me&nbsp;is it also posible that the power transformer could be responsible for this hot spot and the heat simply a direct result of the underside being made of metal? or should i still get&nbsp;the unit&nbsp;looked at?</p><p>Steve</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/11418.aspxWed, 09 May 2007 01:49:03 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:11418Dillen0https://archivedforum.beoworld.org:443/forums/thread/11418.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=11418<p>Steve,</p><p>The Beomaster 1001 (and 1200) uses the bottom chassis plate as a heatsink.<br />If it gets warm within 5-10 minutes you need to get the amplifiers idle current checked, in this case the heat buildup will be more or less<br />concentrated around a pair of the transistors mounted underneath, at least to begin with.</p><p>Normally, after one hour of playing with good listening volume, the whole bottom plate will be &quot;pleasantly&quot; warm ie. not more than handwarm and not particularly concentrated. If it gets &quot;very hot&quot; as you describe, you should have it checked. Should be a cheap repair in that the symptoms are well-known, the components are cheap and fairly easy to reach.</p><p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/11313.aspxTue, 08 May 2007 14:18:38 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:11313canivet2904680https://archivedforum.beoworld.org:443/forums/thread/11313.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=11313<p>I have aquired a beomaster 1001 made in 1973.</p><p>&nbsp;After about an hours use it tends to get very hot on the rear underside of the unit. </p><p>&nbsp;Is this normal for an old amplifier or shoud i take action.</p><p>Steve.</p><p>&nbsp;.</p><div style="clear:both;"></div>
