2022年1月4日 · hifidiy论坛-我的第二级目前用的是苏联的6n6c来调试的，经过和烧友的交流，烧友说kt63好过6v6，后来查欧美胆管资料发现kt63另一个型号是6f6g，现在弄得有点懵逼，到底是用kt63好，还是6 ...

2022年6月20日 · 6F6是一只五极管，最初的原始管就是42号电子管。 6F6是42号的八脚封装管。 有G式（胡芦管）和GT式（直棒）以及美国铁壳管。 6F6的效率低于6V6，内阻高于6V6，输出功率标接为3.2W。 因此6V6问世后，6F6的使用量大大降低。 但6F6过载能力强，板压最高可适用达320V。 尤其是在甲乙2类推挽电路中，输出功率可达19W。 6F6三接做乙类推挽也是过去所常见的。 6F6三接单端输出功率很小，不足1W，为0.8W，所以其三接通常用于做推动放大。 这是现 …

With 315 Volts on the anodes and operated in class A1 push pull, this valve type would generate 10 Watts with 3% distortion. The wide glass tube envelope is 28 mm in diameter and, …

2019年4月22日 · A 6F6 is a 42 on an octal base, one of many that were repurposed like that in 1936 when the "new" metal can octal tubes were intro'ed by RCA. The 6F6G is a direct lift of the shoulder bulb 42, which continued to be used into the 1940s by Philco and others instead of the octal alternatives.

2024年5月7日 · The most famous 6F6 PP amp I know is the Western Electric 133A that uses input transformer to split phase and completely push-pull through out. 349A tube is their version of 6F6G. It does sound good and I prefer it over the more ubiquitous WE 124.

The 6F6G output pentode was designed for audio amplification in radio receivers. The operating values given are for single ended use with an anode load of 7,000 Ω. If a pair are used as an audio amplifier in push pull class A, 10.5 Watts are possible with 3% distortion. The equivalent type KT63 is a beam tetrode.

2008年8月13日 · 6F6 Tubes were used widely in pre war radios and smaller consoles. Ampex 350's use 6F6 tubes.....the 350's are sought after for their big fat sound. Some Legendary recordings were made using Ampex 350's. The 6F6 can be used in many 6V6 applications in my experience--provided the maximum ratings are not thus exceeded for the sub tube.

2018年1月16日 · I can do a pair of 6L6 coke bottles but I can do a quad of smaller 6V6 type, which looks much more dramatic! 6V6G tubes tend to be a lot more expensive than 6F6G tubes, and since I can easily tailor the bias (fixed bias) to the 6F6G, and they seem a good deal cheaper, I've been playing with them instead.

2008年3月9日 · I've got 8 Russian 6F6G types on hand, but am prepared to try new production 6V6's as well..
