Another numbering gotcha: 6CW4 might conceivably be confused with
6C4W. But it won't even come close to fitting in the socket!!!

But rather than guess what typos somebody else may have 
made, this afternoon when I got home I put in
3 6C4W's and the radio works just fine (even bumping up against
some of my local AM BCB intermod sources) with nearly identical
S-meter reading (1 to 2 db higher) than the few-months-installed (and 
50 year old) 6C4's I had in there.

So my uneducated but empirical conclusion: whoever wrote that
6C4W's won't work was obviously mistaken.
