Replaced old fuses in my Dynaco MK IV tube amps that blew from a bad rectifier tube. Who knows how old those fuses were! I bought the 2 amp, 250 volt slow blow fuses. Great price and working well so far! Fast shipping as well.

These type fuses are almost impossible to find in my local rural area. Thanks to AES I can still get them at a reasonable price. Because of the uncertain circumstances of our nations economy and supply chain, I got two packages of 5. Thanks

Brought a 53 year old Fender Bandmaster back to life. Worked exactly as it should.

I was just about to give up finding what I needed and remembered previously buying from AES. I went to their webpage and immediately found what I needed at a most reasonable price, for product and shipping. I received my purchase in record time. Thanks AES!!!

I was tempted to say these fuses really blow. However, I'm totally amped about them.
