Barely DIY - fuse replacement.

[Janus77]

It looks like this fuse is attached to wires going through the board.  How do I remove it?

Unsolder them or snip them out with a pair of cutters.  The wires that is.  then remove the fuse from the clips.

The clips appear to be soldered to the PCB traces.  Don't unsolder these.  Simply replace the blown fuses with clip in fuses of the same rating which look like 10A slow blow 3AG types.  The solder in types are a little more difficult to come by.  Littelfuse make solder in types as well as other manufacturers.

Thanks for the update  now watch this space as I ruin my amp!

Are they end caps or the fuse or separate from the fuses end caps?

 

Kind of looks like they cover the ends of the fuse caps.

 

Disregard the above I now see they type they are.

If they are separate end caps, it’s a very tight fit.

So I can just snip the wires then when I put the replacement fuse in, I solder them together?

[Janus77]

I’ve snipped it out, i think I should have just desoldered it at the fuse cap though now that I have it in my hand.  Ah well live and learn.  Will get and get a replacement fuse tomorrow.

OK, fuse replaced.  Actually the wires holding the fuse at the ends had a common connection to the clips, so there was no need to solder the replacement fuse to them.  An engineer at work checked it and said they normally only use that type for high vibration applications - and was likely only used to scare off the average punter from trying to replace it themselves.

 

Regardless amp is back in action, thanks for the advice Monkeyboi and Muon

Thanks Bob.  I must have had a brain fart when looking at the pics of that board.

Something you dont really see in audio gear! It would be a very small chance the clips were not connected to the circuit, but always good to confirm these things!
