Youre bidding on a legendary Bottlehead Stereomour 2A3 Stereo Single Ended Integrated Amplifier - a factory built 1st generation of Stereomour! Stereomour is a high quality single ended, parallel feed, directly heated triode amplifier kit, a stereo integrated amp with three inputs that can be configured as a 3.5 watt per channel parafeed SE 2A3 stereo amp. The input stage consists of a 12AT7 tube. One half is configured as an actively loaded voltage amplifier using our Camille Cascode Constant Current Source for super quiet, dynamic, linear performance. It is RC coupled to the output stage with a high quality film capacitor. The output stage may be configured for either a 2A3 tube or user supplied 45 tube using cathode bias. A plate choke loads the output tube and the output is via a high quality parallel feed coupling capacitor and parallel feed output transformer configurable to 4,8 and 16 ohm settings to work with a broad range of speakers. The amp uses zero feedback.A custom Bottlehead power transformer supplies high voltage to the driver stage C4S load and output stage plate choke via smooth sounding ultrafast rectifiers and a conservatively designed CRC filter for quiet operation. The power supply components mount on a PC board that attaches directly to the bolts of the power transformer for a very efficient layout.The chassis layout utilizes a new for Bottlehead 10 x 12 format. The grained and laser cut aluminum plate is extra thick to accommodate the new, larger iron. The chassis plate sits in an attractive Pacific Northwest alder wood base that you assemble and finish to taste. Inputs, speaker binding posts and a new IEC style power entry jack are at the top rear of the chassis plate. A easily accessible power switch sits at the top front of the chassis along with volume and input selector controls, and equally easy to access hum balance pots resides next to each output tube.Laser cut chassis plates and alder wood base kits are made for us here in the Pacific Northwest. Our custom Bottlehead power and output transformers and plate chokes come from Northern California. The parafeed output iron for the Stereomour has been newly designed by Paul Joppa for improved sound over the original Paramour iron while keeping at a reasonable price. Rectifiers are ultrafast soft start types. Capacitors are a combination of polypropylene and low ESR electrolytic. Resistors are carefully selected for each application and include carbon composition grid stoppers, 1% metal films for precise voltage and current tolerances, and overrated wirewound resistors for power supply filter and output tube cathode load. The driver stage uses special Agilent LEDs chosen for linearity. Hookup wire includes both Alpha teflon and Carolco insulated 22 ga. solid core copper wire for high voltage connections and Belden solid core shielded twisted pair for super quiet signal wiring.Input impedance is 270K ohms, output can be configured for 4,8 or 16 ohm speakers. We recommend speakers of 96+dB sensitivity for serious listening with all kinds of music. 93 db speakers are satisfactory for less stringent requirements (chamber music, soft jazz, acoustical) and smaller rooms, and we have even used a Stereomour prototypes in our lab with some 87 dB sensitivity monitors for non-intrusive background music. Sonics are hard to describe in print - suffice it to say that Stereomour sounds like the very good SE2A3 amp it is, and our customers have remained enthusiastic about the Paramour design amp for over 10 years now. The parafeed output and C4S active load give the amp a remarkable sense of realism, bandwidth and bass articulation, particularly considering the price.SPECIFICATIONS:Output power: 3.5 WattsBandwidth: -1dB at 20Hz, -3dB at 50kHzSensitivity: full power at about 0.4vHum: ~1 mV RMSInput impedance: 270K ohmsTubes complement: 2 x RCA 2A3, 1 x Siemens 12AT7A free spare Fender 12AT7 tube in original box will be included for free! Can be shipped as a gift with low declared value, so no worries about customs! We have a lot of expirience and be sure youll get our assistance!

Introducing the Bottlehead Crack 1.1 Headphone Amplifier Kit - a must-have for any audiophile! This high-quality tube amplifier boasts exceptional sound quality and is perfect for enhancing your listening experience. This is a partial kit of the bottlehead. It includes upgraded resistors and potentiometer. It does not include the original capacitors or the iec power cable. Buyer will need to purchase parts in order to complete the bottlehead build. Otherwise everything is new including a brand new transformer.

Bottlehead Preamp made from kit. Lightly used and tested with new 6V6 tubes for better sound. Preamp works great - I just don’t use it enough. Base is a stained Alder wood with Bottlehead logo. Brushed aluminum base plate was left unpainted. Transformer top was painted a brown gold color (see pictures). 3 inputs and 2 outputs. For more info see this review from Steve Guttenberg: https://youtu.be/BUYzPzlj8WI?si=lvzypv-pGP6EAj5X.

Youre purchasing / bidding on theitem in the title! From what I understand of this item, is that, these are kits to help Audiophiles understand the process of creating their own Head Amp together. The base stand that holds the top metal sheet where the electronics lay underneath is not secured to the base stand (this allows you to work on your amp) Over the next month or two, Ill belisting some nice quality watches, high end headphones and amplifiers. This isnot part of my regular listings since I post 90% sports cards and memorabilia under my account. The watches and audio equipmentcollection are from a MILITARY VETERAN AND CURRENTLY A PRIEST who I consider afriend. His collection was mostly purchased while he spent his time serving ourcountry overseas. As a priest, he does not have the disposable income or timeto be able to post these items for sale nor does he have the space to store his collection in his humble living area. This person is very meticulous and A type so many of his items were kept in original boxes. Please review any and all pictures forthe quality and condition of each item, but if you need more information orpictures; please request through the eBay messaging portal. Also, if youre interested in purchasingmore than one item, I can combine S&H to try save some money; everythingwill be based upon weight and designation. NOTE: all items sold over$200 will be signature required at the time of delivery to protect both theseller and buyer! And every item will be tested to ensure it powers on/off oris in working condition. Good luck and thanks in advance!!! Disclaimer for AMPS: If unit requires tubes, I dont know how longthe tubes have been in storage or last used. Every amp being sold should havetubes included and will be packed with extra care. Please be aware that you may have to replace one or all tubes.

Up for sale is a completely custom, handmade, one of a kind Bottlehead Crack. I got this specifically and professionally custom built. So many internal parts were upgraded, swapped out for better alternatives, etc. This does NOT have speedball, but many of us in the community feel as though speedball takes away from the tube magic that Crack offers. So, please be aware that this does not have speedball. It was custom painted using violin varnish on the wood, as well as custom creme colored coating on the top plates. The internals have been fully upgraded and heavily modded. Thus, this will not sound like a typical run of the mill Bottlehead Crack. Everyone who has heard it praises it for sounding so much better. For starters, theres an ALPS RK27 10K upgrade. Many resistors were upgraded to Allen Bradley resistors. The capacitors have been upgraded. The last photo of the parts list is what was purchased (aside from the original kit and paint) to make this amp. I paid $800 for this for the kit + the cost of upgrade parts / tubes, and thats not counting labor and assembly. It is in excellent condition. I have used it sparingly and have kept it safely on my audio rack for about a year, where it has not moved from until I photographed it today. It works like a dream. Im including two of my favorite NOS tubes. The top plate is not secured. It lifts up, as you can see, and merely sits atop the base. Someone (Im not the builder of this) can easily secure it better than I know how to. I will ship this in the way that I received it. I received it plastic wrapped in several layers, to keep it intact, and I will ensure it and bubble wrap it very well. See photos for more info.

Bottlehead Crack Headphone Amplifier Speedball Professionally Built. This gorgeous looking and sounding item has been very lightly used, less than 10 hours. It will come with the original tubes as well as highly sought NOS tubes including bugle boy, Amperex, and tung sol. Over $1500 invested into this amp, I have no time to enjoy it sadly.

https://bottlehead.com/product/crack-1-1-otl-headphone-amplifier-kit/ Amazing DIY headphone amplifier works perfectly! Amp includes the tubes provided by Bottlehead....a GE 6as7 and an unidentified 12au7. NOTE: Item is listed for sale on a local marketplace and may be pulled from Ebay at any time. Built earlier this year by me. Selling because I want to build another one with a different color scheme....it was fun! Im a CS guy and an experienced solderer and Im very confident in this build. Prior to building this Amp, I had tried my sennheiser/drop hd6xx headphones with xduoo ta-20 and ta-26 tube amps, neither of which impressed me. In fact, I had put the hd6xx in storage before building this Amp. But now I finally understand what theyre all about. If you have high impedance Sennheisers, you need to try this. In the last 2 photos, I tried capturing a scratch and a couple dings in the wood. I semi-dropped the case (not the amp) when I was attaching the decorative feet. Theyre minor and could be sanded out easily Ill pay for packaging and shipping. Its obviously in my best interest to package it up SOLID!

I have used it sparingly and have kept it safely on my audio rack for about a year, where it has not moved from until I photographed it today. Im including two NOS tubes I have in my stash of tubes. Im selling this as parts / repair because my right channel in my headphones wasnt working suddenly. This is a brand new problem. I tried my headphones on another amp and both channels were working fine, so its exclusively a problem with this amp. My best guess is that a connection became loose or something needs to be soldered back on or replaced. I am not a DIY type of person, so I dont know how to go in, troubleshoot, etc. Someone can very easily figure out what the issue is, swap out a part, etc. to get it to work. Id take it to get looked at by a professional, but, Im moving in the direction of speakers and am decluttering my headphone amps anyway. Since I know nothing of DIYing tube amps, going in and trying to troubleshoot is like rocket science for me. Thus, I am selling it as parts / repair. No returns on parts / repair items, please.
