[K6NCG] Fwd: National HRO-60

[TC Dailey]

Believe-it-or-not, the HRO cabinet was DIRTY, but after I washed it with 
dishwashing soap & water (and a toothbrush), then rinsed carefully.. I 
polished it up with Mother's Car Wax, and it came alive.  The knobs, I give 
the same wash with a toothbrush, then spray some (regular) Pledge in my 
hands and "fondle" the knobs to make 'em not only clean, but look new too. 
There are "some" Nationals with grey knobs that aren't really GREY.  I found 
that out as I was washing some, and they were coming out BLUE.... guess, 
left over from a '270 or '155.

On the can-type electrolytics, I don't even bother to try and restuff 
them... I leave them IN PLACE,  cut the lugs off, and put new caps (much 
smaller) under the chassis.  There are ALWAYS spare screw studs or holes you 
can use (the HRO power-transformer studs are just long enough, past the 
nuts), and I mount threaded-metal standoffs (spacers) on those, then mount a 
terminal strip on top of THOSE.  It makes great place to put the caps, then 
just move the wires from the old cap, to the new ones.. The beauty of it, is 
that you haven't physically changed much, so the "purist" COULD put it back 
to original, if they're that anal.  There IS some guy in ELECTRIC RADIO 
magazine who offers to restuff old cans.. I restuffed one of my own (by 
myself) for a SWAN 350, and all the new "sections" fit in it, but it wasn't 
nearly as pretty as the original.  Interestingly, I've begun to use PC mount 
caps (leads out of the bottom) too, as the leads fit the terminal strip much 
better.  I buy 'em all at MOUSER.

the alignment of the HRO is pretty straightforward BUT, the real "fun" comes 
when you align the coilsets.  Those are "cut n' try", as you CANNOT align 
them IN THE RADIO.  You must make an adjustment, then plug it back in.. try 
it.. then make another adjustment... and on, ad nauseum.  There are about 16 
adjustments on each coilset,... some have less.
