  2. Jp is so far in the lead and I am a close second. Raffy, well he tries hard. Sent from my iPhone using Tapatalk
  3. But wait sports fans, there's more Interesting keynote by Billy Beene (Oakland A's EVP) On stats, the background to "Moneyball", and hanging with Brad & A.J.
  4. Another day in SF, another nerd fest
  5. I was out of it last night and missed the game but the outcome is hawt. We should step on their throat hard and win tomorrow too. Good luck tonight! I may not be able to say that in a couple rounds.
  6. I don't have a complete updated schematic but the hand-draw images below are the changes I traced on the updated Blue Hawaii. IIRC, the rest of the circuit is the same as the original one (the color image). I built the 2SK216/2SJ79 version so replace the 2SJ79 in the drawing with KSA1220 KSC2690 . The KSA1156 emitter resistors determine the current to the third stage and the current is reduced in this version. I will add some notes from my own build later.
  7. 1 ) yes 2) yes 3) the 4 tubes in the middle can either float or tie to -vcc yes the front end tubes are 6.3v, so 1.2 amps
  8. We have chosen.... poorly.
  9. You? Cunty? Never. Love you brother.
  10. Two good races so far, and today the news that Alonso will race in the Indy 500 in May. He'll miss Monaco, but I wonder if he is setting up the next phase of his career, ala Nigel Mansel.
  11. One day last year, while planning my Carbon build, I thought it would be neat to have a dynamic headphone amplifier in a matching case. The Dynahi suggested itself, though I wanted something a little less overkill. Then it occured to me that I might be able to stuff a Dynahi and a Dynalo into one case, and so make an amplifier capable of driving any headphone. So I made this, which I called the DDCA (Dynalo-Dynahi Combination Amplifier): one set of inputs feeding two amps, with separate output protection circuits, separate volume pots, three GRLV power supplies, and one transformer. It was a 3D puzzle to fit everything in (if I were to make another one, I'd position the Dynahi boards right-side up, turned out there is enough clearance that way and it would have simplified assembly) and the wiring took forever (plus keeping it perfectly tidy is beyond my skill). I lowered the gain on both the Dynalo and the Dynahi, since on most amps, I have the volume at 10 o'clock or less, and I wanted to use more of the volume control. Have to admit: the RK50 on the Carbon spoiled me, and the TKD 601 pots here don't live up to it. Not bad, though. Like I posted a couple of days ago, I couldn't bias the Dynahi section as high as I wanted, but even at 0.40V across the 20ohm output device resistors it runs fairly warm, so I decided to leave it alone for now. I also need to get the top anodized black. Maybe add some speaker binding posts... wonder how much of a speaker load I can drive from the Dynahi? Both sections sound great to me, though I don't have an HE-6 or K1000 to really put the Dynahi through its paces. As usual — many thanks to @kevin gilmore and @spritzer for all the designs and boards. This wouldn't exist without you guys. Thanks to @vilts for making matching titanium knobs, thanks to @Zashoomin for getting extra sand with me so we could make matched sets, and thanks to everyone here for group buys and all the help and support.
  12. Rhino 45th anniversary reissue, great sounding pressing
  13. Track bag is packed and ready to go. Sent from my SAMSUNG-SM-G890A using Tapatalk
  14. Noticed Zoë had updated one of her shirts; thought you may enjoy. **BRENT**
  15. It's nice to see, for a difference, that Mercedes now must take care of tactics
