QUALITY AND SECURITY OF "LITTELFUSE" PRODUCTS

One amplifier came in with one of these ’tuning’ fuses which was blown. Usually when the particular fuse location in question is blown, it indicates a service issue, but in this case the amp was fine- once a good fuse (we use Buss and Littlefuse for the most part) was installed. As this fuse was made in Germany, I suspect its the same fuse as Roger Modjesky must have encountered. Even though marked correctly the fuse was not up to its spec! So Roger likely has good reason to not recommend these fuses.

Since the installation of this fuse caused a customer to have downtime and the cost of shipping (about $170.00), I have to agree that these fuses can be problematic! While we are not saying they can’t be used in our gear, I am saying that you may experience fuse failures that are premature. So this aspect should be on your radar should you choose to install such fuses.

1.  Since it only occurred once, probability fuse not up to spec is low IMO. 
2.  Since it only occurred once, possible fuse worked as design and save the amp from damage.   I bet if you install another one, it will work.

Atmasphere, thanks for sharing your experience.

Al refers to them as anecdotal. I prefer to refer to them as evidence. It’s what folks observe, you know, hear. Folks think of seeing as observation usually, but isn't hearing observation, too?  t’s all part of the thing called the scientific method. We have a hypothesis, we test the hypothesis and we accept or reject the hypothesis based on ob-ser-va-tion. It’s actually remarkably simply. As I am fond of saying, it’s the preponderance of the evidence that counts. And there certainly has been a bunch of that,

There is an exception to every rule. Of course, there are any number of perfectly good reasons why you didn’t hear a difference. Shall we explore what those are? ;-)

Geoff,

Thanks, Peter. I frequently see those three words used together.
