First Try Diy

Don't use slow blow fuses with batteries, use fast blow or even better Resettable fuses (ask your local electronic component shop). Last mentioned is smaller and are reusable.

the batteries on some of the battery backed up supplies I use come with slow blow. So it doesn't blow on initial current spike.

Yes those are PTC-types (positive temperature coefficient) and not like ordinary glass type slow blow fuses. They first go into high resistance due to internal temperature rise, and when the over current persist they blow.

I'm going to look into those resettable fuses. I'm assuming they work like a trip switch?
While building my amps, I must have gone through at least 20 fuses while prototyping. Sounds a lot, but duel rail, with 2 channels.

Go to www.Bourns.com - all the info you need - most local component suppliers stock them.

I had a look at the data (see below) it will work and safe up to 10A (+/-30W)

yup, will hopefully get a few of those soon
