Hi, maybe someone out there can help me out. I'm looking for a chip that N ational Semiconductor produces. What i'm trying to make is the Dynamic Noise R eduction circuit presented in this months issue of Audio magazine. I have all of the parts except the DNR chip. The number of the chip is: LM1894N DNR. I really don't feel like spending $35.95 for all the Semiconductors in the c ircuit (an offer they make in the article), when all i need is one! Also i'll need an adjustable coil. Its number is: 4.7mH adjustable inductor, Q=35 at 19kHz (Toko cln20-740HM) If anyone can help me to locate a distributor, or if anyone knows where i ca n find these i'd appreciate if you left a note in my reader at GOT AT PSUVM. I 've looked all around this area, and no one knows where to find the chip or th e inductor. thanks ..... Sunil Gupta (GOT AT PSUVM)
