117Z6GT Vacuum Tube – Dual Rectifier / Voltage-Doubler for AC/DC Radios

The 117Z6GT is the GT-envelope version of the 117Z6 — two independent rectifier sections sharing one 117V heater, wireable as a full-wave rectifier, half-wave rectifier, or voltage doubler.

• Tube type: Dual-section rectifier
• Heater: 117V AC/DC, no transformer required
• Typical use: Flexible rectifier stage in transformerless AC/DC radios and three-way portable receivers

Electrically identical to the 117Z6, differing only in envelope shape.
