GU-70B

Description

The generator tetrode GU-70B in ceramic-metal design with an indirectly heated oxide cathode and an external anode with forced air cooling is designed to amplify a single-sideband signal with an output power of up to 250 W, as well as to amplify power at frequencies up to 250 MHz and with an output power of up to 125 W in stationary and mobile radio engineering devices for industrial purposes. Decoration - metal-ceramic.
Cooling - air, forced 45 m3 / h.
