[Johnson] ranger fuse

[w5htw]

Thank about it.  Using a three-wire cord, with the 'green' direct to 
chassis, and a fuse in each leg,  it doesn't matter what goes wrong.  
Reversed polarity, shorted bypass capacitor, (if after the fuse, as it 
should be)  bad wiring in the house.  It doesn't matter.  The chassis 
cannot get "hot" (unless you put a 40 amp fuse in there!.)  If the 
transformer primary shorts, the fuse blows.  There's nothing wrong with 
fusing the neutral, and I advise to do it.  Reversed polarity somewhere 
- and you don't know what some electricial did in your fuse box or wall 
outlet years ago, especially in an older home - will not be unsafe, and 
won't matter to the operation of the radio.  It will still work, it 
won't be "hot" and if anything goes wrong, a fuse blows.   I can't 
imagine NOT fusing both sides of the line, using a three-wire cord with 
hard-grounded GROUND. 

There is one caveat, though.  That ground, that green wire, MUST go to a 
real ground.  That can be your ground prong on the wall outlet, 
certainly, IF that prong is really ground.  Easy to check.  Or it can be 
a solid earth ground, good strap to a rod deep into the ground outside 
your window.  Or both (though there is some fear of creating ground 
loops for RF if you do both, but it can be done.) 

Go for it.  Fuse both sides of the AC line, but make SURE that ground is 
really ground.

Ed, W5HTW
