[R-390] Need straight poop on 6C4

[Craig C. Heaton]

To All,

I've got a 6C4 going soft in the RF section of my R-390A. The Y2K manual
shows to use a JAN-6C4W, another source states to use a 6C4WA, the 6C4W will
not work, the 6C4 will work but not quite as well.

So, need the straight poop, which 6C4 is the real deal? Got a guy 20 minutes
down the road with a house full of tubes to sell.

Thanks & 73's
