I have assembled a simple ampilfier (a kit one from jaycar electronics) and to be honest it sounds like crap. It distrots the sound horribly and is very scratchy.
In the instructions it is not specific as to what power source to use, so i used a 9-volt battery. The instructions describe one of the tests as to measure the voltage over certain parts, whilst the voltage i measured follows the trend (one a basically half of the other), the values are not the same as indicated in the instructions.
I measured 7.6 Volts and 3.75 respectively and the instuctions say they should be 11.4V and 5.7V respectively.
I assume that the amplifier therefore needs a 12V power source (which i don't have at the moment).
Could this be the cause for the wretched results that i get when using it or is it more likely to be a dodgy soldering job or something similar?
thankyou for any help
