Thank you Ratch and Harald.
Much appreciated.
The signal injection and tracer looks like the best approach here. But obviously like you say Ratch we should always start with a general "whats wrong and where" analysis first as this can often bring attention to the faulty component(s).
Okay yeah I've seen a few videos on signal tracers. The one in particular i've seen was of a guy using it to test a bass guitar amp. I wondered if this might be good way to go whilst testing a mixer so you have just confirmed that for me. Thanks.
Hi, i'm learning about checking the voltages across components during fault finding. I know how to calculate the total resistance and current of a circuit and thus use that with ohms law to calculate the voltages but I'm now wondering what if the circuit was AC. In particular im looking at audio...
hi Could someone please tell what the cuboid shaped beige components in the attached image are please?
The ones with the black writing that says '1j63' on them and the one with '33j63' on it.
Thanks a lot
Hi,
Just wondering which potentiometer taper is generally used for the cut and boost control on an audio equalizer.
I know that for normal volume controls we use logarythmic taper but i'm wondering is this the same for let's say... a 'bass' control on a hifi amplifier which has a centre point...
Just because I've got loads of 10k pots lying around at home not being used whereas i would have to buy the 5k ones in especially. It doesnt matter tho. A bit of patience and a bit of money spent will result in a proper job so i'll just do that. Thank you very much for your help tho.
This image doesn't really help at all. We need to see the connections (on the reverse side of the board) and preferably a schematic to go with it. You could just hand draw one and take a photo using your phone. Then upload it.
