As a consequence the filament power is about 10x the 1j24!
I have some, but the 1j29b do more power than a DL94. I did make a single ended amp and a push pull amp.
You can triodise them and use two to replace the earlier PX4s, or the later ones if running life not important. Also work to VHF in class C or push pull. An earlier version was used in the Sputnik in class B/C push pull.
Also were used for pulse radar 800W on shells and bomb proximity fuzes. Life of minutes.
