Bottlehead Electrostatic Headphone Amp
This Bottlehead Crack headphones amplifier is not a new news but still hot for sure. For some reason, this amplifier is always praised by DIY'ers as the best headphones amplifier so far.
Not just because it is tube, but it is sound good. If you not knowing this amplifier before, you need search the manual first. This Bottlehead Crack headphones amplifier is sell in a kit and luckily for you living in States, this kit can be obtain with the ease. But not for me living in Asia, the delivery cost for this amplifier will high and takes much time. This Bottlehead Crack amplifier here in this post is lend by my friend.
He bought it in used condition and He is willing to stop by to my home yesterday to let me check it first. Quick inspection, this unit is having the original components, especially for the transformer. Quite dirty for sure, I will cleaning it up in return and maybe some cosmetically upgrade later on.
As you can see, the top plate is quite dirty. The transformer cap has some rust on it. But overall still in maintained condition. The wood panel on side is loose to the top plate, means no any screw locking both parts together. I also don't have any idea what should I do to attaching them. I guess using glue will help. Here in the internal components from today quick inspection. It is all tidy, it is all original except the potentiometer has been upgrade to ALPS blue.
I see some additional resistor after the potentiometer. It is 1 kilo ohm, usually for improve amplifier input stability. I will try to remove it later and return to it's original as per schematic.

I am new to tube amplifier and having this in my table is something rare. As usual, the tube amplifier have a common looks, they exposed the tube itself. It is beautiful. Not only to showing it without any purpose, it is like the heat-sink on the solid state amplifier, the tube exposed for release the heat by surrounding air circulated.
This Bottlehead Crack is overall very simple presentation, only a power tube and a front line tube along with the power transformer and all input output connector on the same surface. I do some testing with simple setup. I am using iPod as source and Sennheiser HD headphones. Once I turn it on, the power tube start glowing. It is reach normal temperature about 5 minute and it is warm.
My initial impression with this amplifier is sweet sound. High dynamic with sweet sound on overall music frequency. The bass a little bit late in my opinion, perhaps it is because less power output to drive this HD, but overall quite satisfying. After this quick check, it is time for me to disassembly all components. Start from the tube first. Email This BlogThis!

Building the Bottlehead Crack Headphone Amplifier: A Comprehensive Guide
Log in or Sign up. Mufflore , Dec 21, Last edited: Dec 21, I'm not going anywhere looking forward to it. A couple of interesting changes: The mild mains hum on the headphone amp is gone. When music isnt playing it is dead silent now. This must be down to the valves breaking in, they have probably hrs or less on the clock.
Tube Amp Under $1,000
The S. Meanwhile the Crack OTL output transformerless headphone amp has set a new standard for exceptional sonic performance from high impedance headphones at budget prices. Last year we retired the premium Smack headphone amp kit. There were a lot of really sophisticated aspects to that kit- adjustable output impedance to handle a wide range of headphones, both single ended and balanced headphone output, a single gain stage circuit with active loading and hybrid shunt regulation, and very good transformers. And very good sound — Doc B. Unfortunately for Smack we revamped the S. And we somewhat compromised the kit with a very functional but standard stereo volume pot to keep the price down. After having the Crack and then adding the Speedball CCS update, I have always wanted to see what Bottlehead would do with a TOTL headphone amp…so after a few years and many headphone amps I bought a kit and wanted to share the attributes of this wonderful amp as well. I have used headphones from 32 ohms to ohms and there is more power in SE or balanced output to drive them very well, to painful levels. It has 2 RCA source inputs, which makes it nice to flip a switch and test 2 different source inputs.

This thing is like a nice glass of Bourbon for my ears, and I wanted the pictures to reflect that vibe. Bottom line: The perfect pairing for my Sennheiser s. I bought the kit about two years before I started building it. I had a few other projects to work on before this one, so in preparation for it I spent weeks online reading through many of the help posts on the Bottlehead forums, looking for the most common issues people have while building these and I also researched upgrades and other modifications for it. A good first project would be one that deals with low voltages, like a simple pocket amplifier that can run on batteries and not one that has the potential to seriously injure or kill you. I bought some of the tubes even before it was finished and in the process, I also improved my woodworking skills. The wood base has 8 coats of danish oil wet sanding the application of all but the first coat , with drying and sanding in between each coat.
