Whether you want to fix an old radio or need a perfect gift for an amateur radio fan, the RCA 6AV6 vintage tube and tube socket is an excellent choice for quality sound. This made-in-the-USA, high-quality vacuum tube is built to last. Produced by former electronics giant RCA, the tube is just as reliable now as the day it was manufactured. Ideal for radios, televisions, and amplifiers, professionals know that the 6AV6 is an excellent choice for any electronics tube need. The 6AV6 is a miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor and is capable of providing a relatively large, undistorted output voltage from a very small input signal. The 3AV6, 6AV6, and 12AV6 are alike except for heater ratings and heater-cathode voltage ratings. The 12AV6 is particularly suited for use in AC/DC radio receivers. As a result of its controlled heater warm-up characteristic, the 3AV6 is especially well suited for use in television receivers, which employ series-connected heaters. When the 3AV6 is used in conjunction with other 600-milliampere types, which exhibit essentially the same heater warm-up characteristic, heater voltage surges across the individual tubes are minimized during the warm-up period. While some say the 12AX7 is interchangeable with the 6AV6, the two vacuum tubes operate on different voltages and circuits. Thus, the 12AX7 is not an identical replacement, and you would need to do some alterations before dropping a 12AX7 into a 6AV6, or vice versa. The RCA 6AV6 is a miniature seven-pin double-diode triode in a glass envelope with black plates. The vacuum tubes were made starting in 1947 in the USA. The JAN variations were produced under a joint army-navy nomenclature. The 6AV6 can be used interchangeably with common models, including EBC91, 6BC32, and CV256. The forerunners to the 6AV6 were the 6SQ7, 6AT6, 6SQ7GT, and 7B6. Don’t be content just to gaze wistfully at your cherished 1980s television or ham radio and sigh. The search is over with the 6AV6. Now you too can experience the thrill of powering up your old radios, guitar amps, preamps, and television equipment again.
