Totally agree.
The circuit for it was from a US magazine and for a single pentode acorn valve with 120v HT and a 6v battery for the heaters.
Mine uses 2 AA Ni-Mh and a little inverter that gives 100v, very neat indeed, I've the filaments in series via a limiter resistor. Like any super regen it's quite fussy so I put it in a tin box, it is actually quite loud and really sensitive.
