Clearing out some extra parts.

For sale are some chipamps that are "drivers". Just add some capacitors, resistors and output transistors and you have a 200WPC amplifier.

First up is the LM4702. I have 4 chips and 2 boards made by member dfdye, see these threads-

Thread #1, Thread #2.. Also see the National Semiconductor Application Note #1, Application Note #2 (MOSFET output stange), and Application Note #3.

Next up is the LME49810. I have 4 of these for sale. This is also a 200W driver chip (No board avail for this one). Its a newer chip with better specs and performance. The National documentation and application notes are available Here.

Prices
LM4702s and boards are $10 + 10 + 5 (shipping) = $25
LME49810s are $10 + 5 (shipping) = $15

Here are the LM4702's and the boards.
