Synergistic Research Orange Quantum fuses X 4, rated at F 12.5A 500V
These are 32 X 6mm fuses, which I purchased for the DC power rails on my Conrad Johnson Premier 350 power amp (now sold).
They are in "As New" condition, with no wear and tear indicated.
The 500V rating means that they can be used in voltages up to that rating, so perfectly suitable for UK 240V mains voltage.
Popular posts on the internet indicate that when buying SR fuses for Fast Blow use, that the rating should be over-specified by 25% to account for current in-rush, hence me purchasing 12.5A rated fuses to replace the stock 10A standard fuses.
There is no such adjustment necessary when considering SR Slow Blow fuses, which should be replaced, like for like, according to the rating of the original standard fuse.
The SR Orange fuses are £155 rap. Asking £75 each or £275 for 4.
