Youtube interview with Dennis Had (I have one of his Firebottle HO amps) where he laughs off the fuse thing
Like to see this wolf, got a link, might need some backup Ordnance one day.

BIG fan of Nelson here, starting with DIY B1 buffer, as great as people have written about above. Had F4, aleph 30 and now F7, best of the bunch for me so far (xa25 is on my wish list for the future). Had many other amps too but his class A designs combine all the best qualities for an incredibly satisfying listening experience. He is so generous with his time and advice, answering emails and writing on forums, great sense of humor in his writing too (wish I understood it all!) and that never ending curiosity driving him to the next innovation - wonder what the sit-3 will be like.
I have pass gear.  I call them from time to time for some suggestions and he still answers the phone on occasion.  Great guy and very knowledgeable.
Ran an Adcom 555 for many years before I could afford to move on, bullet proof, clean and adaptable to many systems. Just great midfi that brought many hours of music. Nothing like it for the money, I’d say.
