Hi DefQon,
Thank-you for both your offer to assist and your advise. As for assisting me, I am a resident of Canberra so I am a couple of thousand kilometres from Queensland, so it is most likely that I will be doing the repair myself. But as for your advise, thanks so much, I am glad to hear from an experienced and knowledgeable person. I will follow your advise and replace the 8 resistors and NOTHING else. Although I want to ask if there is any other thing I should check or assess while the circuit board is out of the unit? Do any other components get as hot as the resistors? And should I consider fitting a larger fan or somehow increasing the air-flow? I want to fix this amplifier and make it last, that is why I spent extra dollars and had Mundorf Capacitors fitted when the amp was built, to hopefully increase the sound quality, but mostly to make it last a long time. But here I am with a six month old amp that has a burnt resistor. I asked David at Little Dot if I could supply him with any other parts to upgrade the unit when it was being built, but he said the capacitors and silver wire was all that was needed. I would have been happy to send some resistors as well at the same time that I sent the capacitors and wire, but it is to late now.
