Hi Everyone.

I'm having an issue with one of my 9444A power amps.

At every second or third power on, it immediately blows the main fuse. Other than that, functioning fine.

Altec spec 'normal blo' ceramics, which is what I have in it. It has been restrapped for 240V, and I've double checked that is correct.

I suspect inrush current as a possible cause, any thoughts on if 'normal blo' actually refers to a slow blo fuse, as opposed to a fast blo. Interestingly the 9444B manual recommends slow blo fuses.

Thanks
Nat
