Extras ▼

 

The RCA 5734 is described as a mechano-electronic transducer. The top of the body can rotate about the rest by ±0.5 degrees and this rotation alters the anode to grid spacing and this the anode current. Thus the design is a transducer that responds to vibration. The 5734 can work up to 12,000 cycles a second.
The valve was measured with the protective sleeve in place.
