Its only a fuse right? The new BLACK fuse is now available from MCRU. We could write a lot of hyperbole to promote the product, instead we just simply advise you to fit these and rest assured you have acquired the BEST.

The fuses are 20mm diameter to fit inside your equipment, please see notes below.

At MCRU we receive 100's of enquiries for 20mm fuses, we cannot stock the entire range.

If you have decided to purchase a 20mm fuse you must first replace like for like, so for instance 3.15A slow blow

is fitted to your equipment, replace it with the same rating SR fuse. 

An order will be placed with Synergistic Research every month for the fuses our customers have requested so if you

place an order today and we do not have the correct size/rating it will be between 1 and 30 days before your fuse arrives.

That is a fair way to save us having to spend £10,000+ on fuses stocks that many customers won't ever use.
