Are C6 and C8 wrongly marked? Should their locations be swapped? |

We made the stethoscope but instead of LM386 we used LM380 and instead of TL072 we used LM381 as in another book it was written so.. but in our output while using loudspeakers the volume is too low.. we didnt do the volume control part.. we attached an led in parallel wid speaker to check if the circuit is working, the led keeps on blinking but loudspeaker output is too low. also instead of a mic we used a crystal pick-up cartridge. do we need to shield cable the 3 wires from the pick-up cartridge? please respond asap! thanks! |
