Well, I went down & shut off the valve, then backed off the nut slightly. Began to leak more, so I opened a nearby faucet to remove pressure on the outlet side & the leaking stopped. I slacked off the nut about half way; no leaking, so it seems I may be able to repack the valve w/o shutting off the outside water control. I'll go to the hdwr store & see what they have for this before proceeding further. Plus I'm having to soak the screw that retains the valve handle in penetrating oil to get it out w/o risking breaking it off. Ironically, after all this when I reopened the valve, the leak has substantially quit.
No doubt not for long, however.
When it comes to plumbing, I'd rather do electrical ;-)
