Tube DF 96 or Röhre DF96 ID451, Vacuum Pentode, Miniatur-7-Pin-Base B7G, USA 1940 and RF/IF-Stage shown. Radio tubes are valves.

The DF96 is a miniature amplifier pentode with very low filament consumption. This Mullard valve from 1953 has half of the filament current of its predecessor the DF92 . It was specified for use as an IF amplifier in portable radio equipment.

Feb 18, 2012 · In the late 50s and early 60s there were magazine articles on how to replace the 1T4 / DF91 series with DF96 series tubes to double LT battery life. The most change being the series dropper resistors for LT on mains sets.

The Russian Miniature Rod Pentodes are a completely different family, in this article we only consider the Domestic B7G tubes. Some of the Ediswan/Mazda numbers are the same as completely unrelated octal valves (tubes) or Ballast tubes.

Jun 6, 2024 · I want to make a crystal oscillator using DF96 vacuum tube. The tube is a small RF/IF amplifier for battery operated systems. This tube is unique in the sense that it only takes 25ma of filament current.

Aug 29, 2010 · Pentode gain + triode cathodyne makes a lovely 6V6 PP amp. Bit of a stretch for 6L6, but quite doable. Not quite enough gain for NFB, you'll need a preamp to get away with it.

Nov 14, 2015 · I find that in some power amplifiers with a first stage pentode (and GNFB to that cathode), the screen bypass cap goes to ground/common. This instead of to the pentode cathode (commonly, classic pentode operation means that the screen should be at cathode a.c. potential).

The DF96 is an amplifier pentode for use in battery portable radio equipment, mainly domestic broadcast receivers. By 1954 the transistor was the next approaching technology and Philips, who owned the UK Mullard company, responded with a range of 25 mA filament valves.
