I roasted a couple of opamps yesterday, fed them too many of the volt thingys. While waiting for a new pair to arrive I thought I'd balance the output fets and see if there was any noise(you can tell I was bored)....well there was noise: to the tune of 230 uv wandering between 18 and 23 hz...

I don't think I'm going to lose any sleep over this, and the layout of the boards is fairly spacious so I wasn't expecting perfection, nevertheless I'm curious. Can anybody hazard a guess where such noise might come from?

Is it not likely to be 1/f noise?

I've just sneaked a peek at 1/f in relation to fets....I'm outta here

but thanks for the heads up, from what little I understood of the description it looks like you're on the money.
