So you want to build a little one tube regen with low B+? This regen I just finished is based on MRL’s 1-Tube DC All-Wave Receiver, HB-4. You can order the handbook from MRL here

If you build this receiver remember to isolate the headphone jack from the metal front panel or use nonconductive material for the front panel.

I built this regen for the 40 mtr Amateur Band, the schematic below reflects the changes I made to the circuit.
