That is interesting because as I mentioned the filament in the ARC sp16 is clearly asymmetrical as I recall so it should be easy to specify which way to insert that into the fuse holder mounted on the back of the unit "correctly" by the pre-amp maker who should know.
Oh well, there is always hope still for a non-believer I suppose. At least I get to choose my own favorite fuse direction or not bother at all when I can’t tell a difference. That is more convenient than there being a "right" and "wrong" way for sure and maybe getting it wrong I must say. The customer is always right........
OP BTW thanks for not banning the cynics from your thread like some fuse threads in these parts and giving us someplace we can roost and banter perhaps for the benefit of those whose minds are not made up.
