20x5mm fuses

20x5mm fuses to suit Amp Maker fuseholders and projects

For the integrated IEC and fuseholder socket and the separate fuseholder, you need to use 20x5mm fuses. This selection covers the most typical types and values for guitar amp projects.


Dimensions & info

All fuses are 20x5mm. They may be glass or ceramic, depending on whatever the supplier has in stock (it doesn’t make any significant difference, of course.) I stock slow-blow types for typical mains-side use and fast-blow types which many amp builders like to use to protect other parts of the circuit. Choose the right type and rating of fuse for your project!



Amp Maker is now closed for the 2020 Christmas holiday, and will re-open in early 2021. See News section for details.
