Which SR Blue or black Fuse

@geoffkait 

What are you talking about? Ramtubes is talking about aftermarket fuses wrecking equipment because they don't do their primary job. 

Look .. if you want to buy the snake oil and risk fruit your gear, have at it. But why spend $50 to do what a 2 cent piece of 16g wire will do? If you're not worried about killing your gear, just bridge the fuse holder with a piece of wire or bus bar. If you are worried about frying your gear, use a fuse proven to do it's job. This kind of analysis takes no brains. If you are chasing aftermarket fuses as solutions, you're just gullible. 

What did you think I was talking about? Just curious. Otherwise, excellent bloviation. 

There was a thread a few years ago regarding aftermarket fuses and the possible dangers of using them. The subject was not about whether or not there is an audible difference vs. stock. 
Many of our resident experts participated and the result was there were no reports of components being fried or catching fire if the proper value fuse was used.

@glupson I recently had an AC fuse in my IEC connector blow when switching from triode to UL mode. Turn on and switching surges popping fuses is not as uncommon as you may think.  In fact you can search the forum and find others here posting about it over the years.
