THE 832 DUAL PENTODE VHF TRANSMITTING TUBE MAKES A REALLY NICE REGENERATIVE RECEIVER. THE CIRCUIT REQUIRES A HI-Z HEADSET. EITHER THE OLD STANDARD 2 TO 4K OHMS TYPE, OR PIEZO HEADPHONES WILL WORK. I'LL INCLUDE A HAND SKETCHED SCHEMATIC DIAGRAM OF THE CIRCUIT, PLUS A BLOCK DIAGRAM SHOWING WHERE TO HOOK THE ANTENNA, HEADPHONES, ETC.
