GK-12A

Powerful generator triode GK-12A in ceramic-metal design with an external copper anode and forced water and air cooling.

Designed to amplify the power of high-frequency oscillations at frequencies up to 30 MHz.

The GK-12A triode is used to work in electrothermal installations and other stationary radio engineering devices.

It is produced in a glass-to-metal design with a directly heated tungsten thoriated carbide cathode.

Working position - vertical, anode down.

Forced cooling:

  - anode - water at least 17 l/min;

  - legs and balloon - air at least 300 m3/h.

Overall dimensions of the GK-12A triode:

   - lamp height - no more than 400 mm;

   - diameter of a lamp - no more than 190 mm.

Weight no more than 15 kg.
