Description
Powerful generator triode GU-68A with a tungsten thoriated, carbide directly heated cathode and water-cooled anode. Designed for generating and amplifying power in stationary radio engineering devices of wide application at frequencies up to 30 MHz. Design - ceramic-metal with ring leads of the cathode and grid.
Cooling - forced:
— anode — water 120 l/min;
— legs — air 200 m3/h.
Details
1. Filament current 315 ± 15 A.
2. Cathode emission current (at Ua=3 kV) ≥ 220 A.
3. Anode current ≥ 8A.
4. Grid current ≤ 3A.
5. Grid turn-off voltage is negative ≤ 400V.
6. The steepness of the characteristic (at Ua=1 kV, Ia=10 and 14 A) 130 ± 15 mA/V.
7. Gain (at Ua=1 and 2 kV, Ia=10 A) 34 ± 4 mA/V.
8. Vibrational power at a frequency of 30 MHz (at Ua=12 kV) ≥ 250 kW.
9. Interelectrode capacitances:
– input, no more than ≤ 160 pF,
– output, no more than ≤ 3 pF,
– through, no more than ≤ 55 pF.
10. Heating voltage 19 – 21 V.
11. Durability, not less than ≥ 2000 hours.
12. Triode weight: 24 kg.
Payment & delivery
All shipments are carried out from our international warehouse in Dubai (UAE), as well as from our partners’ remote warehouses.
In Stock — items available in stock at the Dubai warehouse are dispatched within 5–10 business days after receiving 100% prepayment.
Remote Stock — items available at our partners’ remote warehouses are supplied within an average of 30–45 business days after receiving 100% prepayment.
Pre-Order — made-to-order products are manufactured and delivered within an average of 45–60 business days. Payment terms: 50% advance payment to start production, with the remaining 50% paid before dispatch from the Dubai warehouse after full readiness for shipment.
Returns & Changes (Restocking Fee)
For selected items, a RESTOCKING FEE of 10% may apply in case of return, order cancellation, or changes to the order specifications. This condition applies only to certain products and is confirmed at the order approval stage.
Warranty
All products are covered by a standard 6-month warranty.
Extended warranty is available upon request and is agreed individually; it may affect the final product price.
