For 230V operation, connect primaries in series by connecting black and re lead wires together and apply 230V across yellow and violet leads wires. For 115V operation, connect primaries in parallel by connecting yellow and red lead wires together and black and violet leads wires. To parallel...

What happens when you touch the 2 leads together? It should read 0 ohms. red and black oriantation won't matter for ohms testing. It will matter for voltage tests. Red positive Black negative Also check out Tangents video on how to use a multimeter: How to Use a Multimeter

Reflow your solder joints. sounds like loose connection

Yup. check out Tangents "Notes on Opamps"

tl082 but needs more than 9 volt to operate.

Sounds like a ground loop. 1st Plug the sub into the same power strip 2nd Did you try lifting the ground on the sub?

lm386 Is a cheap audio amp chip. Rather noisy and the gain is bit high, 20 db. Is really a tiny speaker amp but is used for headphones.

Did something similiar for a cellphone and ipod setup. http://www.head-fi.org/forums/f6/sou...ircuit-230855/

Its a cmoy. Has 4,7K resistors for railsplitter instead of the middle of the battery.

xinfeed: I believe itgoes between source and amp.

Your wife give you the honey do list yet?
