[GreenKeys] Fuses for model 15

[Bruce Gentry]

Unfortunately, trying to find standard edison base plug fuses is 
becoming very difficult. They are illegal in many localities for use in 
a building electrical panel, so electrical supply stores often don't 
keep them. I don't know of any prohibition on using  them in radio 
equipment.  In many cases, exhisting fuse panels must be retrofitted 
with permanent adapters that will not accept a fuse larger than a 
certain size. Once the adapter is screwed in, it can't be removed 
without great effort. A spring wire barb grips the shell of the socket. 
I think you can modify these adapter by finding and grinding off the 
barb so it won't ruin the originality of the Teletype machine, and get a 
newer "non-tamp" (non-tamper) fuse of the correct rating from a BIG 
industrial electrical supply to screw into the adapter. I have also 
taken blown fuses, torn the tops off, and used them to make adapters for 
standard glass AGC/3AG fuse holders. Find a chassis mount glass fuse 
holder that has a spring in the cap so the terminal on the end doesn't 
move. Wire it into the old plug fuse body, and fill the old fuse body 
around the new fuse holder with epoxy. It lets you use modern fuses 
without altering the equipment. I personally don't like using circuit 
breakers as the only means to protect motors, so using a chassis mounted 
circuit breaker instead of a fuse holder in the homebrew adapter is 
probably not a good idea.  A few thoughts from an industrial control tech.

   Thank you and your  friends for working to preserve the  Battleship 
New Jersey.  Not that many years ago, duty on a battleship was 
considered the best in the Navy. Battleships may be obsolete in some 
ways, but they represented American pride and craftsmenship that are on 
the verge of being lost.
