[Boatanchors] 4CX-350J Tubes

[FRED - W4FJF]

 Good Morning All,
    I have 8 sets of 4CX-350J's (chimneys and sockets, too) and wonder what I can do with them. 2 or 6m amps? Any ideas, or construction articles come to mind? I wouldn't mind a good signal on 6m, so I would be really interested in that. Any B/A amps use these tubes? I bought them from Fair Radio Sales years ago, listed as N.O.S. RCA. Appreciate any info you can supply. You can contact me off list at w4fjf at yahoo.com.
