Condition of all the fuses are excellent.
The SR RED small 4amp was used in a VAC Signature MKIIa pre. There's nick on the outer surface when removing from the fuse holder but doesn't effect SQ. SR fuses have a soft shell so easily nick with some fuse holders. The SR RED large, used in ARC REF250 and Hegel H30, are perfect ... a different style fuse holder that doesn't require clipping to insert/remove the fuse.
