Soundcraft powerstation manual

It was touching against LK96 anyhow so I've fished it out and re-seated it the same as the others. Can you suggest my next step? Should I drive the amp with a signal and trace it through with the oscilloscope, or work through testing the components as per the service manual values?

Since you have a good channel to play with do a side-by-side comparison of DC values with your meter. You can then move on to doing so with a scope and the same signal fed into both channels but there will come a point where the presence of negative feedback will start to blur the picture. If the output is distorted then you'll get a distorted signal fed back to the input via the NFB path which in turn will distort the signal being fed forwards.

Thanks Brian. I'll get on that this evening. This is going to sound very much like a beginner sorry Should I use a common ground such as the leg of R1 and then measure the DC through the amp chain as Brian says, comparing the good amp chain with the bad? I don't want to be the cause of additional component damage! The left channel has this physically smaller resistor for FR2 which measures 68ohms. Just right of the words 'Stereo Power'.

Could this cause a problem? I assume the resistor on the right channel is larger in size for a reason. Any resistor labelled FR is a Fusible Resistor ie one designed to burn out in the event of a fault. The one on the right channel looks like a previous repair using the wrong component because that isn't a fusible resistor. Once you hook it up to a scope a useful indication of where the problem might lie will be what the output looks like. So I thought I'd start with the real basic oscilloscope tests.

I put a Hz sine wave through the amps and got it on the scope from the leg of R Which gave me this on both amp channels. So a nice clean signal coming in Then I put the probe on the speaker output of the left channel which gave this. Oh dear. Finally I touched the probe between D1 and D2. The left speaker instantly became clear! Putting the probe back on the left speaker output now gives me this I'll remove the suspect diode, clean it up and re-attach it tomorrow.

Thank you. Originally posted by Oddeohead View Post. If it still won't get loud enough, it's probably broken. I'm here to make it. Originally posted by eschertron View Post.
