Products of uncountably many $k$-spaces

It is shown that if a product of nonempty spaces is a &-space then for each infinite cardinal n some product of all but n of the factors has each n-fold subproduct n-X0-compact (each n-fold open cover has a finite subcover). An example is given, for each regular n, of a space X which is not n-N0-compact (so Xn+ is not a A:-space) for which Xn is a A:-space.
