Fortunately, I live near a MicroCenter which tends to be good enough for most needs that arise, but I sorely miss being able to go to a store and get a replacement for a specific capacitor etc.

With RadioShack long gone, we are forced to improvise.

That was my first thought after reading the OP lol. You have to hoard now that the Source of all things weird, old and/or obscure is gone.

Damn, you just reminded me that I should probably check the battery in my genuine RadioShack multimeter…
