Well that is all the noise I got from over ten hours of recording. My first thought was that it was the fan for the heater (it was 12F outside last night), but I ruled that out since the noise was so short and did not occur more often. I also thought that it might be the amp that I made, but that makes no sense because it was not able to be reproduced.

The amp I am using is simple LM386 circuit, not the quietest I will agree but it does a good job. I have ordered some TL072, TL052 and NE5532 amps to see if they make a difference. Unfortunately the LM386 is the only low power amp chip I have, the others are 50-300 watt monsters (still not quite sure where or why I got them).

I just listened to your diode noise sample and that is exactly the noise that I typically get and the base I use for noise removal. Glad to see that I was on the right track there.
