For fast delivery of goods, kindly please read following tips carefully before order:

Since this triode is high value and Customs declarance necessary,
for compliance with China foreigh exchange policy.

the Payment need to be paid through TT to our company bank account,
therefore, please DO NOT pay the order directly online.

please contact EECTECH through sales@eectech.store BEFORE order / BEFORE payment, we will help you to complete the order and payment fluently in a short time. thank you.

Introduction:
1. FU-928F is a high-power transmitting triode, coaxial cermet structure, forced air-cooled anode, direct heating thorium tungsten cathode. The operating frequency is 30MHz, the anode power dissipation is 40kW, the grid power dissipation is 1kW, and the output power is 60kW.
2. The tube is mainly used as an oscillation tube in industrial high-frequency dielectric heating equipment and as an amplifier tube in radio equipment.
3. The cathode of FU-928F electron tube, the filament adopts soft lead, which simplifies the installation
