Tube 6D6 or Röhre 6D6 ID2690, Vacuum Pentode, 6-Pin-Base U6A, old, USA and RF/IF-Stage shown. Radio tubes are valves.

The 6D6 (=6U7 on IO base) is a variable μ pentode for AGC controlled amplifiers at RF and IF in superhet radio receivers. Electrically the 6D6 (UX6 base) is identical to the Type 58 (UX6 base). The paper band around the top of the envelope is printed with the words - quality approved - special export test.

The 6D6 is a variable μ pentode for AGC controlled amplifiers at RF and IF in superhet radio receivers. Electrically the 6D6 (UX6 base) is identical to the Type 58 (UX6 base) and the 6U7G (IO base).

Tube UZ- 6D6 or Röhre UZ-6D6 ID25309, Vacuum Pentode, 6-Pin-Base U6A, old, USA and RF/IF-Stage shown. Radio tubes are valves.

Tube 6D6_Octal or Röhre 6D6_Octal ID43178, Vacuum Pentode, Octal (Int.Octal, IO) K8A, USA 1935 and RF/IF-Stage shown. Radio tubes are valves.

A radio frequency pentode for radio frequency and intermediate frequency stages. Six-pin plastic base with top contact for control grid. Suppressor grid brought out to a separate base pin.

The 6D6 is a variable μ pentode for AGC controlled amplifiers at RF and IF in superhet radio receivers. Electrically the 6D6 (UX6 base) is identical to the Type 58 (UX6 base) and the 6U7G (IO base).

6d6 Quality IF and RF amplifier tubes manufactured by various makers in North America. These glass shoulder type pentode tubes, equivalent to VT-69, 6U7, and 58, come with 6 pin bases and top grid cap.

Dec 19, 2024 · The 6C6 is a sharp cutoff pentode with a shorter, steeper curve. It provides good amplification and would be easier to drive into nonlinear operation if detection is added to its duties. "Hell, there are no rules here--we're trying to accomplish something!"
