  1. Further information: Bought new from A1 Futureshop last month. Excellent balanced headphone amp with 12AU7 tubes. The TA-20 compared surprisingly well to the Mjolnir 2 and is a touch warmer. Have a Cayin amp incoming so need to sell some gear.

  3. Further information: I bought three sets of Philips NOS tubes from a fellow SNAer a few weeks ago to see which ones suit my preamp best. They all have relative strengths. This set has good bass and is much better than the current production Mullard, but they are not as nice as the other two sets. So I decide to sell these 3 tubes. I have used them for about 10 hours. From the faint code, I gather that they are made in Hendon Works, Alberton, Australia in the 50's. Photos:

  5. Further information: Quad or really 2 pairs of RFT EL34's which have been tested on a hickok 750 tester, they pass gas and shorts and all test above new spec and all within 5%. One pair has the RFT boxes and slightly bigger base, The other pair has no boxes and has a sligtly thinner base. happy to split the pairs if I have a buyer for both. Structurally they are essentially the same. They all are the single halo getter type. RFT stands for Rundfunk- und Fernmelde-Technik - a group of state-owned technology companies in the former German Democratic Republic (East Germany). T
  6. Tube amplifier homemade? With this post, I would like to advise all of you who believe that output transformers must be purchased that there is an alternative. Purchasing or reusing 'lacqer-insulated' copper wire can be used to make your own output transformer with the help of a computer program created by Yves Monmagnon. Here are two videos where I first make a chatode biased amplifier, then rebuild it into a fixed biased amplifier. In the last video, each tube is checked to be adjusted, and then the entire amplifier is benchmarked with the help of an ocilloscope and RMS voltmeter. Here is
  7. To get a grasp of where I’m am going with this thread you need to of read or have read this article. https://www.stereophile.com/content/gramophone-dreams-34-salt-cellar-system If you go no further at the least it is in interesting read. Some will go “meh” others will take it on board to search for better reproduction. Maybe even build there own SC. The challenge I have given myself and would like to throwout to others is can you build or hobble together a “Salt Cellar“ (SC) system. The core of a SC system is purity of sound, dynamics and immediacy. These are t
  8. Right now there seems to be a wealth of opportunities in the realm of tube audio here on SNA. Lots of top quality gear at excellent prices. Or am I biased, having just gone further down the tube path?
  9. Further information: Smart looking in vivid red and even better sounding SRPP tube preamp. Built on a Hammond Wood cheek chassis with external PS. A 24V wall wart (provided) powers the PS which joins to the preamp via a heavy cord. Tubes are Gold Lion Gold pin E88CC.

  11. Further information: This is essentially a preamp with a gain of 1.0. I feed my DAC into it, then output to my amplifier. It adds a tube distortion to your signal, which can make it better. Eric Chan made it for me by request. Looks funky, as all Eric gear does. It features two RCA inputs, one RCA output, and a switch to change between the 6as7 tubes and 5998 tubes. I also have several tubes that go with it, including a WE421a that is now worth a lot on it's own, and these i include at no extra cost. if you are looking for low cost high quality entry into tube wor

  16. Further information: PRICE DROP!!! I'm surprised this hasn't had as much interest as I thought it would given its relative rarity and glowing reviews. I would really like it to go to someone who will use it (I've even sold my headphones!). I suspect I've priced it too high for the market so taking a hundred off. For sale is my gorgeous headphone amplifier hand crafted in Japan. It just doesn't get the use it deserves. It is in wonderful condition, and has heaps of glowing praise bestowed upon it by the doyens of the internet. Look it up!
  17. Hi there, First, I am a newbie here. I wish to have advice on the pre-amp. My current setting is MacBook Pro --> AQ DragonTail --> Curious Cable --> Chord Hugo 2 --> Sennheiser HD 600. I use Audirvana to listen hard drive music and Tidal. Hugo 2 is nearly the best of portable DACs, and HD 600 is already nice enough for me (of course you can upgrade to Audeze LCD-2 or 3). Here's my question: I listen a lot movie soundtrack and 60s/70s classics (the Beatles, Elton John, Leonard Cohen, you name it). I listened some tube amps giving warm sound for me. I am think
  18. Further information: The original Genalex Gold Lion ECC82 / B749 / 12AU7 is one of the most rare 12AU7 tube types ever made. The Genalex 12au7 tube featured superb linearity and extremely low noise. The reissue Genalex Gold Lion ECC82 / B749 / 12AU7 tube features gold plated pins and has been carefully engineered to recreate all of the attributes of the original. The Genalex 12au7 tube is a premium replacement for all 12AU7, ECC82, 5814, and 6189 tube types. Bought last year for 220.00 from tube audio but never got around to using them. thanks for looking.
