  1. Thank you! I have probably around ten hours or so of listening time in so far. I really, really like what I am hearing.
  2. Thank you for all the kind words. The attenuator and selector is from khozmo which is the component division of hattor. This attenuator alone is amazing, but it really shines with the ACF-2. The casework is is a passion of mine, it allows me combine metal and woodwork. I get better with every project. while this pre-amp may not present a sonic improvement to every system, it has greatly improved the sonics of mine.
  3. So... after what feels like forever I have finally completed this build. I had to make many changes along the way, but I am happy with the final product. After A great deal of listening I decided the SP-14 circuit was not the best for my system. Too much gain. So I sent it on it’s way and went a different route. In the spirit of keeping this system all tube I opted for a ACF -2 octal from glassware. This is a buffer. There are many options for tubes, but I decided to use 6sn7. I was originally splitting my source signal to an amp for my speakers and sub. This sounded good, but now it sounds much better. The bass is cleaner and my speakers have an increase in detail. I am very happy with the sonic results. I would definitely recommend this project to anyone running multiple amps or driving long cables. The best best part is I can toggle between sources again without having to change cables. That was getting annoying.
  4. No, it is a glassware acf-2 octal buffer. Dead silent at idle. So far I’m really happy with it. I will I’ll be in touch about about a 2a3/300b project.
  5. I saw you posted on diyaudio too. I was disappointed to see that the dg300b boards were no longer on neurochrome.com I too was planning on undertaking this project. I was going to wait though until my pre amp was complete to order boards. I finished it Sunday. Bummer. Best of luck on the search for boards. I have already started looking for alternative 300b or 2a3 projects. Will
  6. Very, very cool!! I would love to learn more about these. FH1 bottom I assume?
  7. Very interesting. a unique idea, and beautiful implementation. nice!
  8. Check out the parks audio puffin. It’s like a Swiss Army knife. I am super happy with mine. The sound is fantastic. http://www.parksaudiollc.com/ btw, it is paired with heavily modified la Scalia clones, a clementine set amp and a pro-ject rpm 5 carbon table with mc cart.
  9. What a cool video! Those people are artists. The glass work looked effortless, however I suspect many years of practice has gone into that process.
  10. Great, now I am thinking about them again🤔
  11. Good. I can stop thinking about them.
