You can take the Apache and DX100 modulator circuit diagram, and replace
6CA7/EL34 and 1625, respectively, with 6146's, change the sockets, raise
the screen voltage, and it'll play fine. I tried them in my DX100, and
found conversion to EL34s was plenty good for that rig. Of course, as
someone mentioned, the Valiant had a pair.
