Hello,

Because many request about a new group buy for the PCB of the ultra-low THD oscillator from the AN67 from LinearTechnology, i open a pre-order list for a 3nd group buy.

All related info about this ultimate oscillator design can be found at this thread:

If you are interested, edit the wiki page of the group buy that you can jump here: [2nd round] AN67 Ultra-low THD 10kHz sine oscillator PCB Group buy. - diyAudio

Finding parts...

Hello,

Some people ask me where to find the LT1230 IC for building the oscillator.
The LT1230CN (DIP) is not obsolete, but it seem to be hard to find on usual IC sellers.
I can give you various solution,
The first is to buy it on ebay here : LT1230
The price is good!
Second, you can ask sample parts directly to LinearTech HERE.
Third, you can buy the easy to find SMD version, and solder it on SMD to DIP adapter like THIS.
(Iif you are skilled, you can do it yourself!)

I hope that will help you a little. :)

Frex.
