There was a guy at the Marathon hamfest selling NOS Sylvania 6146A's for $15.00 apiece. I got four so I'll have spares for the KWM-2 that's in my future. ;) He had a lot more & it's probable that I'll see him again at this hamfest in February or at other times during the year. Let me know if you'd like me to pick some up for you.
I really only need two, and will be happy to pass along the other two. The guy said they're truly NOS -- never been used. Instinct says says they're just fine -- but the usual caveats about these kinds of transactions apply.
But when I get the Cheyenne going (only radio I have so far that uses those great tubes), I can check them in that.
Well, can't get rid of the image...didn't notice "gas" written on the box. Hmmmm.....now I wonder....
