Description

The tube GM-70 modulator triode is designed to work as an amplifier of low-frequency oscillations in modulator circuits. The location is vertical. Cathode tungsten thoriated carbide direct heating. Anode – graphite.

Closest Equivalent: 845 tube (requires circuit modification as pinout and operating voltages, especially filament voltage (20V), are different from standard 845 tube).
