  1. You could make it slightly more complicated with the help of a laser turntable.
  2. That is a "Copenhagen V" headphone amplifier. Power supply is external.
  3. I might need to fire my photographer, but here's something new.

    Mattresses

    We did end up buying the hand made, foam and latex free bed. It was over the top, but, after daily back pain for years, to suddenly realize my back has not hurt since the day we got it has made the price worth it.
  5. Speakers look great, but I'll never understand the desire of woodworkers to hand make things out of natural materials only to coat them in plastic.

  7. I own that Forrest blade, and if you look at the copy closely it says it cuts nearly flat bottom grooves. It still cuts little bat ears. It's good enough for an unseen groove to fit a drawer bottom as there is enough flat to hold glue, but it is not nearly good enough for joinery you can see. The Freud ripping blade is tons better as it is truly flat and just suffers from a little tear out as it dulls. (It's real fault is that the kerf is ~0.128".) Ridge also makes an ATB+R that might be a bit better than the Forrest, but still is not perfect. As far as I know, the Ridge 40 tooth FTG is a unique blade.
  8. It was lovely. It's supposed to snow on Monday. I'm pretty excited about that blade. It is, so far as I am aware, unique - it is a 40 tooth flat top grind with a precise 0.125" kerf meant for doing joinery. Every other flat top blade is either a ripping blade with fewer teeth and a less precise kerf, or has an 8" diameter and is wider.
  9. On high Z, the L2 has a Zout of something like 50 Ohms. The headphones have an impedance of 80 Ohms at 1KHz, but 300 Ohms at 50Hz. That means there is a voltage divider with the headphone Z and amp Z. So, if there is a 1V signal, at 1K about 38% (50/(50+80)) of that signal is lost to the amp's impedance, and the other 62% goes to the phones. So you are left with a 0.62V. At 50Hz, the amp is still 50 Ohms but the phones are 300 Ohms. That means they get 86% of the signal. That's nearly a 3dB boost at 50Hz. Hence too much bass.
  10. I'm skeptical about remastering - I can't say I've ever really heard a remaster that I thought was much better, but I have certainly heard plenty that were worse. This one feels pretty easy to get wrong. But I am excited about the re-release of the old demo tapes. That should be fun.
  11. There might be albums out there that are as good, but I am doubtful there are any that are better.
  12. Sometimes flipping toroids will reduce stray fields.
  13. While I cannot speak to the rest of New England, having spent winters in Minnesota, Wisconsin, and upstate NY, I can say that people in Connecticut* cannot handle their weather.
  14. You can cut a hole in the bottom plate under the PT and then add a small plate underneath to fill the gap. It will add the thickness of the plate to the interior which appears to be about enough, and it will be hidden.
  15. I've certainly chucked an end mill in a hand drill to chop out something small when I was too lazy to dig out the dremmel. But even of the drill was OK with the side force, it is not fast enough for milling.
  16. Sounds like you might need more amplification ... edit: D'Oh. Same joke, and your version is better.
  17. They are that, but they are available. DSHA3 and DSHA3F (specifically for Focals, picture below in walnut) are the current models, and Tom and I are very close to releasing the T5 which is effectively a DSHA output stage with tube gain. Indeed, I just received an updated T5 power transformer in the mail today that I soldered in not 10 minutes ago.
