2013年1月19日 · The 6BQ7A is a miniature, medium-u, twin triode primarily designed for use as a cascode radio frequency amplifier in very high frequency TV tuners. In this application, its performance is characterized by low noise figures and high gain. From the piccie, it's obvious that this is indeed a high frequency triode.

The 6BQ7A is an all glass miniature VHF double triode and is internally screened. A valve like this would be used for RF amplification, or frequency multiplication. In the latter case the valve is operated as a non-linear (Class C) amplifier. This causes harmonics of the signal frequency to appear in the anode current.

2005年7月28日 · If I had to build an amplifier using only these tubes, I would use the 6BQ7's for voltage amplifiers (and a phase splitter if P-P) and the EL86's or 6CL6's for output depending on which type I had the most good ones of.
