Luxman m-03 m03 strange fault....


2005-07-25 12:35 pm
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!! :)
