My luxman m-03 has a strange behaviour. It sounds good, but when it goes hot (after about 30 mins) it sounds dull, i.e. it 'cuts' high frequencies on both channel. Any help?
It's a problem of thermal runaway...but what check?
I don't know if the idle bias is correct.
Does it'd be the oxidized contacts of the output relays?
Any help appreciated!! 🙂
