Anyone,
I have built a small Headphone Amp for the purpose of amplifying musical instruments to Headphone Levels. The amp I’ve used is a very small Kit for a 0.5 Watt Amp, and works well. My problem is the big pop when I turn it on or off.
From my limited understanding of electronics, I was under the impression that a Cap of sufficient size would fix this, but the circuit already has a 100uF across the +ve and –ve terminals of the circuit board, and doesn’t seem to do anything.
What I would really like is, to be able to switch it on and have the Volume increase over a period of say 2 seconds until the full volume is reached. (I have a pot that controls this).
Is this possible, and how?
Thanks,
Graydon
