I can hear a very low noise (into speakers) when I sleep in my room (so it's very low but when I turn at max volume, it increases).
How can I remove this thing?
Is it a "random" noise (like the inter-station FM noise), or an "oscillatory" noise like motorboating? IF you havent' used the supply bypass caps which national semiconductor recommends -- THEN use the supply bypass caps which national recommends. (100nF in parallel with 10uF).john_lenfr said:My problem is:
