Audited Supplier JINGGUANG 3CW20,000A7 is a high-performance ceramic/metal, water-cooled power triode designed for use in zero-bias class B RF, audio amplifiers. Operation with zero-grid bias offers circuit simplicity by eliminating the bias supply. In addition, grounded grid operation is attractive since a power gain as high as twenty times can be obtained. The 3CW20,000A7 is electrically identical to the air-cooled 3CX10,000A7 except for its 20kW plate dissipation rating. The anode and grid flanges provide ease of mounting regardless of application. JINGGUANG 3CW20,000A7 is manufactured in the JingGuang Electrical Manufactory. JingGuang has achieved the improved performance described above with exact Replacement compatibility with the 3CW20,000A7 manufactured in the United States.
