Hello folks, I recently got hold of a Crack kit with the Speedball upgrade, it needed building and I built it as I was told by the nice instructions. The voltages are all around those on the sheet but once up and running for a while, it starts to fizzle through the headphones. I thought, go back to basics and check all my solder joints, did so and then found that the two resistors that bypass the headphone socket are partly burnt and one of them has even melted part way through the white cable going to the socket, as it was touching the resistor. Are these supposed to run that hot and what could possibly be causing them to run so hot, if they are not meant to? Apart from the Speedball, the kit is as it came, just not a bag of bits anymore...
