Will an amp manufacturer honor a warranty with one of them in their product sent back?

I could tolerate "blue" level. Reality is Littlefuse for $2.00.





In this case my own built in biases would make it hard for me to evaluate.
This is definitely a point of diminishing returns.  I don't think any one of us here would likely spend more than $175-225 for a single fuse.  That being said, if you own a Bugatti Veyron, then this could be an option for you!!
