A check underneath, where you can actually touch the fins showed it was burning!</p> <p>Anyway, it turned out to be the no-load trimmer (what else?, as the great (?) George C. keeps saying), which was new but another &quot;bare&quot; model, was getting dusty. A good clean and re-set was all it needed. The voltage at the testing points was 150 mV instead of 22 mV!<img src="http://forum.beoworld.org/emoticons/12.gif" alt="Angry" /></p> <p>WHY ON EARTH do these uncapped trimmers have not been eradicated from the planet? <img src="http://forum.beoworld.org/emoticons/02.gif" alt="Big Smile" />&nbsp;Nothing but trouble. And they are EVERYWHERE in B&amp;O stuff!</p><div style="clear:both;"></div>
