Description
Powerful modulator triode GM-3B. Designed to amplify low-frequency oscillations in cathode-coupled circuits in stationary radio engineering devices. Decoration - glass-metal. Working position - vertical. Anode cooling - forced, air (at the outlet air temperature not more than 25 C) 800 m3/h. Weight - 4 kg.
Details
1. Filament current 150 ± 10A.
2. Anode current (at Ua=1.5kV, Uc=0) 3 ± 0.6A.
3. Anode current in a pulse (at Ua=3kV, Uc=0) 8 ± 2A.
4. Emission current per pulse (at Ua=Uc=1kV), not less than 25A.
5. Reverse grid current (at Pa=7.5kW Ua=6kV), not more than 0.3mA.
6. Slope 22 ± 5 mA/V.
7. Gain 9 ± 2.
8. Anode current cutoff voltage (at Ua=4.5kV, Ia=0.5A), no more than 600 V.
9. Interelectrode capacitances:
– grid-cathode, no more than 30 pF,
— anode-cathode, no more than 4 pF,
– grid-anode, no more than 30 pF.
13. Heating voltage 6.0-6.6 V.
14. The temperature of glass and metal junctions with glass is 150 °C.
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.
