lm386 mod questions
« on: April 02, 2009, 09:48:25 AM »
I am waiting on the parts to arrive for this mod and would like so info please. 

1.  if I decide to use more leds then the standard 2 mentioned in all of the tutorials will I need to change the resistor size?

2. If I want to add two small speakers to the umd can these be fed from the lm386 as well as the leds?

3.  if I want stereo on those two speaker do I need a second lm386 added to the system?

Please believe that I have read and read and read every tutorial and comment I can but the more I read the more I get confused.  thanks

1. the resistor value should be fine, but I'm not sure about wattage. I think the more leds u have connected, the higher the wattage needed. But I am not sure.

2. Yes, but I heard using a capacitor in the circuit would help stop distortion. There should be a diagram somewhere within the first 2 pages of this section.

3. a 2nd lm386 is needed for the 2nd speaker. Otherwise, both speakers will have to be mono.
