B&K M200 fuse

[Jsped]

Hi Everyone. I have B&K M200 mono blocks that I inherited. Initially, they powered up, but there was no sound. It turns out that the fuses were bad. So, I bought new ones at Home Depot. They now work, but the fuse cap needs to be pressed in order for it to work. Are there different size fuses for the same capacity? Any ideas?

Thanks!

There are different physical sizes but they are vastly different, for example 20mm and 32mm.

Probably tired spring and/or corroded contacts, those push in/screw in holders aren't great

Is there an easy fix?

I presume it's the speaker fuses? Simplest thing would be to try contact cleaner, see if that does the job

Thanks everyone. The fuse holder is a screw-in know. It doesn't stay tight enough to keep the fuse in contact. What a spring help? I don't have any at the moment.

I'd either renew it with something similar, or more likely replace it with something better like this http://uk.rs-online.com/web/p/products/0417098/?tpr=3
