Where do you buy fuses?

shawn474

I need a couple types of fuses for my B&K amp and I can find one of them at Radio Shack, but am having a hard time finding the other. The two that I need are:

4 amp / 250 volt slow blow
12 amp / 250 volt slow blow

Does anyone know of a site that I can use to buy both. I want to get a unch of replacements just so I have them on hand in case I blow a couple fuses again.

Thanks in advance,
Shawn

Have you checked in isle 4 across from the black paint?:cheesygrin:


I would check out Parts Express or Mouser Electronics.

Thanks guys; just picked up a couple packs of each from Parts Express. I don't know why I didn'yt think of them before; I have used them in the past and totally forgot. Thanks again.

Parts Express is great!!

NAPA autoparts has a decent selection if you ever need one right away.

OH MY CLASSIC......

I never knew how spoiled I was until my local TV/ Radio repair shop owner died. That guy only bought USA made fuses and had everything you'd need to repair any tubed TV or Radio.

Once upon a time you could get any fuse needed at RS but that has all changed...They need to change their name to monster cable phone mart

OK, so i have a B&K AV5000 amp; in the owners manual, it states the following:
"Replacement fuses:
Line -12 Amp/250 Volt Slow Blow
Rails - 4 Amp/250 Volt Slow Blow"

My question is what is the difference between the "line" fuses and the "rail" fuses? I am linking a schematic as well if that helps (it is from diyaudio.com). There are a pair of fuses for each channel; one on top and one on bottom. Just not sure the differentiation and I don't see the fuses marked that I want to replace.

Thanks in advance,
Shawn

Shawn, they are not line or rail fuses but part of the circuitry in you amp. Line fuse is for the line side of your amp, ect..

OK, this is not computing......:redface:

Maybe I can take a picture of the guts and you can explain it? I just want to replace the actual fuses, which I think are all 4A/250V slow blow fuses. Am I not correct in assuming this?

Thanks (and picture forthcoming),
Shawn

Picture as promised; thanks again for the help. To the left of the picture, you can see two fuses - one on top and one on bottom. Are both of these considered "rail" fuses?

Ya might try Grainger

shawn474

Yeah; they all had 4a/250v stamped on them, but i could tell some had been previously replaced. Just wanted to make sure they were right and saw the manual listed two fuse types. Just trying to figure out which is which.

Chances are those are both rail fuses. The symmetry of the components leads me to believe they are there for the positive and negative rails. The line fuse will likely be on the main AC line. I am surprised that it has a value of 12A though. That is some serious juice that thing needs. You cannot have anything else besides that on a 15A circuit if its the AC line fuse.

Makes sense now; thanks a lot man. Appreciate the input and explanation.
