Description

Thank you for visiting our shop

Buy 2 pieces, 4 pieces, 8 pieces = exact matching (matching group). No parameter drift

Regarding matching, all our tubes are matched in the factory production workshop. The match is accurate (not all tubes are matched). We have the conditions and advantages to match multiple tubes (four, eight, ten) according to customer needs. The parameters of the two tubes are the same)

High-quality products. Precise matching. Quality assurance for one year

Note: (After receiving the tube, please do not think it is a fake or shoddy product).

Ultrashort wave machine bile duct FU-811

811(FU-811)

Directly heated thorium-tungsten cathode high μ tube triode 811 is used for high frequency oscillation power amplification. 811 is similar to 811A and can be used interchangeably

Filament heating

Uf …………………………6.3 V

If………………………………4 A

Limit rating

Anode voltage……………………1250 V

Anode current……………………125 mA

Anode dissipation power………………40 W

Gate current……………………50 mA

Operating frequency and anode voltage

When the working frequency is above 30MC, the anode working voltage and anode input power will be adjusted down according to the following table in due course:

Operating frequency (MC) anode voltage and anode input power

60 89%

80 70%

100 55%

The anode is not allowed to have a reddish color during continuous operation. When it is operated intermittently, the anode can only have the reddish color just noticeable.
