bandmaster fuse?

[cream123]

I just took this amp home for the week or so and I realized (thank god, I realized it) that it doesn't have a fuse....

what fuse type should I use. It says 3 amp on the backplate...

2 AMP fuse from Radio Shack and you are set. It wouldn't have mattered if you noticed it or not. The amp wouldn't have turned on without it and eventually you would have noticed it.

B Bent is too busy buying and selling stuff to read your post. j/k

You're right - the amp says 3 amps, as do all the schematics you'll find for 40-watt 2x6L6 Fenders. What it doesn't say is that it needs to be a 3-amp slow-blow. When you power an amp on, there is a momentary inrush of current that can exceed 3 amps. The slow-blow fuse forgives these short surges, and only blows on sustained (more than a few seconds) overcurrent conditions.

Glass slow-blow fuses are easy to distinguish - they are the ones with little coils inside that look like springs. Regular fast-blowing fuses just have a straight wire or metal bar.

Get a 3-amp slo-blo. Radio Shack should have them.

Rich.............. I guess I have lived safer for my amps all these years because I have always used 2 amp fuses and never had any of them blow. Cream... listen to Rich because he is much more experienced in this than me. I wonder why I have never blown fuses? I guess to small is better than to large huh!!!
