K8060 preliminary test

Hi, I need help!
I assembled my K8060 200W power amplifier kit and I tried the preliminary test by connecting a 60W light bulb in series between the line and the transformer.
What happens is that the lamp flashes for less than one second and then it stays off. Is it a normal behaviour ? Can I go ahead and replace the lamp with the fuse?

Thanks in advance.
Another question: Is it available a velleman kit for a guitar preamplifier?

Yes, that is normal.
