[Boatanchors] 4CX-350J Tubes

[Glen Zook]

The original Hallicrafters HT-33 (NOT the HT-33A or
HT-33B) used 4CX300 series of tubes.  You might be
able to use basically the same circuitry for an HF
linear amplifier.

The manual is available from BAMA.

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?
