Default Re: Which signal generator?

Just replace the fuse.

Fuses die of old age and turn-on surges. The rated current is that which nominally takes 1000 hours to blow. Time/current is a curve, from milliseconds to years.

You might be lucky. If it pops the new fuse then investigation is needed. It's all semiconductor with regulated power rails and might not take kindly to dim bulb powering.
