Mika Väyrynen---Hi! I'm repairing yamaha stagepas 300 amplifier/mixer which has a problem with left channel making crackling sound. Short video of my problem is shown here: https://www.youtube.com/watch?v=DGmbwmNCyzU. Any clues why this would be happening? It gets worse when the device gets warmer. Perhaps something wrong with the feedback loop or the filter section? Any help is appreciated where to measure or what general components to check with multimeter/oscilloscope? Thanks!

Everything is fine, except I don't get much bass out of it. is there anything that can be done to improve low frequency components of the circuit? Thanks beforehand. -> here is the reference circuit: https://goo.gl/nDC0wc

Carol WillingI saw on your Amp Hour interview that you were using Raspberry Pis for testing. Can you share what you are using them for?
