[net.audio] NEED HELP FINDING "DNR" CHIP!

GOT@PSUVM.BITNET (02/22/85)

   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)
