6j23P Pentode Tube Indirectly Heated Oxide Cathode High-Frequency Amplifiers

Description

6j23P Pentode Tube Indirectly Heated Oxide Cathode High-Frequency Amplifiers
Pro note: "6j23P with a triode - a very pleasant, detailed sound and does not ring. Mode: at the anode 200V, cathode current 40mA, cathode resistor about 50–60 Ohm, bias voltage about 2.5–2.7V"
The 6j23P pentode is designed to amplify high-frequency voltage in broadband amplifiers with signal separation at the output.
Indirectly heated oxide cathode.
Works in any position.
Produced in a glass finger design.
Service life not less than 2000 hours.
The base is pin with a button bottom.  9 pins.
