Headphone impedance and Bottlehead Kits
2010年3月15日 · The two kits - the S.E.X. kit and the Crack kit, are rather different animals. The S.E.X. kit is a more traditional single ended tube amplifier of 2 watts output that can run very sensitive speakers (like 99dB or better) and headphones ranging from 4 ohms impedance on up to several hundred ohms.
S.E.X. 3.0 - last eight kits! Special tubes included.
2024年9月5日 · That said, as an end user one should have little trouble locating a pair or two on ebay, or from reputable tube vendors - if you ever need them. The tubes last a long, long time in this amp. We have set aside a special batch of premium …

2016年6月10日 · The Kaiju 300B amplifier kit has been getting a lot of positive reviews as an exceptional amplifier.

6C45P tube Rolling - Bottlehead
2015年3月15日 · It is an awesome amplifier. I upgraded the components last week, e.g. replacing the 10uF capacitor by Auricap 18uF as per Loquah. It was a positive upgrade, the overall signature of the amplifier was kept with enhancement in smoothness in both mid and high tones. I read the thread about tube rolling.

Stock 2A3 Tube Life Expectancy - Bottlehead
2011年1月14日 · It runs everyday as my wife is a stay-home mom. I suspect it has 800+ hours on it now and have been wondering about tube life expectancy. I know from previous tube amps that power tubes tend to age slowly and you may not notice it for awhile. This is my first Bottlehead amp and my first experience with the 2A3 tube.
Crack FAQ - Bottlehead
2013年5月22日 · The simple answer is that we don't like the way that they sound. We have built a few Cracks with tube rectifiers, and they did not have the dynamics or low frequency command that the solid state rectified Cracks do. Adding a tube rectifier to this circuit requires a different power transformer, different power supply, and different chassis ...
Tube Rolling w/Crack - Bottlehead
2021年6月15日 · A 6AS7 will work just fine. The 6080 tube (usually shipped as stock) is a ruggedized version of the 6AS7. Electrically, they are the same. You can also use a 5998 or 7236 (which is a computer rated 5998), though they are harder to find these days. I'm not familiar with the 6520 tube, though it's often included in the 6AS7 "family."
