The discussion, about agc chips a few days ago resulted in a design, using the NE570 or SA571 chip from philips. Does anyone have 1 or 2 spare NE570 or SA571 chips he wants to sell? (DIL package prefered) I tried to order from arrow, but they charge $50 for international shipping a $1.50 device. (usps shipping rate is below $3) Please send your offer to tbw@gmx.ch Thanks! tino -- http://www.piclist.com#nomail Going offline?
