May 01, 2013  Bottlehead Crack Coppermine Edition I’m going to guess that the Crack is Bottlehead’s all time most popular kit. A great little tube headphone amplifier at a price-point nearly anyone can afford that sounds very good for the money, it’s really hard to go wrong here. The Crack has gone up in price a little bit since its introduction 3. That’s basically what Bottlehead has done: they have a slick website, they support forums for their users on major audio websites (and you’ll need them, believe me), and they provide quick, friendly technical support to help you figure out where you screwed up your kit. And that’s how they got to be the most popular tube kits on the market. The third is three-quarters complete but they have provided a part which doesn't match the instructions or schematic. I have parts which I can use or do they want me to use the part provided. I have emailed them but it may be 24 before a response.

• the input tube is a 12AU7 and the output tube is a 6080 (6AS7); possible tube rolling in both positions

• the output impedance of the amp is about 120 ohms (1/Gm of 6080), meaning it works best with high impedance headphones (120ohm+)

• large electrolytic coupling caps mean you will not suffer from a high pass cutting your lows with low impedance headphones (though damping factor would be low)

• CCS loads for the 12AU7 and 6080 (Speedball) is available as an optional upgrade Activate microsoft office 2013 crack.
