I have just completed the k8060 amp kit and powerd it up, everything seems fine, but i cant set the bias across r19.
Nothing happens when i turn vr1. why?
Everyrhins seems to be in order,nothing is burnt, smoking or getting hot.
The fuse is alright and i get + & - 45V on the rectifier diods (to much?) and 8.99v on the “9V-diod”.
Don’t know if matters but ive mesured 0.02V over r20.
What can be wrong?
