I tried the connectors at back and front panel, same problem.<br />The mic is confirmed in good working condition.<br />Is it due to motherboard? It is Intel DG965RY. Or driver?<br />All functions of this PC including headphone are fine except this mic issue. <br />Could anyone please help? nfk Technical Support Thu, 04 Jun 2009 16:11:19 +0800 http://forum.lowyat.net/topic/743614 I bought the musical fidelity x-can headphone amp from a forumer. <br /><br />The amp was ok except some transistors are quite hot.<br /><br />Recently I opened it to have a check on the temperature of the transistors, however I saw some brown marks on the PCB around the legs of the transistors. I think this is not a good sign due to extreme temperature. The amplifier is still working though.<br /><br />I am thinking to send it to someone who know this amp to have a look. I called the local distributor but I think the phone number is wrong. <br /><br />Additional information: I listened to the amp not more than 10 times and each time less than half an hour. I only swept one of the tubes and the transistors around that tube seems to have more serious problem. <br /><br />Hope some of you can help or give me some advises. Thanks for your help in advance. nfk Audiophiles Wed, 16 Jul 2008 11:19:42 +0800
