Perry -

The Vishay CCF60's are nice 1% resistors (and surprisingly
cheap!) but if you actually had some in your hands you might
decide they are not what you want to put in your radios.

In my humble opinion, the Vishay PR01/PR02 or maybe the
Mouser-sold Xicon's (261- or 282-'s) would be more appropriate
if you wanted to do replacement of typical 10 or 20 percent
1/2W, 1W, 2W carbon comps.

The above is just my personal opinion but I am not a big fan
of 1% resistors except where the extra precision is actually needed.

(There are some 1% resistors in a 390A, I know, and I wouldn't
be opposed to the CCF60 or CCF55 as a replacement there.)

In many tube-based projects (repair, refurb, and from-scratch)
I've done in the past few years I've been very happy with
the PR01's/PR02's/Xicon metal-film varieties.

Tim.
