Andrew,
Thanks for your offer. I ordered a new SLYDLOK fuse holder and fuses from The Fuse Company of England yesterday. They no longer carry the old wire fuses or holder. Apparently the new ones are indistinguishable from the old ones and more reliable.
I am working on completing the electrical circuit and have no plans to work on an actual wireless installation in the near future.
However if you can share some pictures of your filter, fuse holder and wiring, I would appreciate it. My original reference picture before disassembly is less than perfect. I will have to also have fabricated a cover for the fuse holder since mine was missing.
Peter
