  1. is it anything like the final countdown?
  2. found an error with the input board, fixed and updated
  3. 2x is just fine for this
  4. i'm sure they can make a high quality amp. But they are subject to the same parts i use unless they find piles of obsolete parts. Kind of doubt they would do that at this point
  5. maybe it will look like this. makes the rsa stuff look ok.
  6. i'm looking at my board which is labeled 2009 Jacob potter and all the electrolytics go from power rails to ground
  7. Its there now, I put it in the wrong place
  8. so if I count right, that is 50 resistors per string. which would work out to 25 resistors (sign + 24 bit magnitude) x 2 and then 2 of them which would be balanced for one channel. so it actually could be really balanced. 3 opamps at the outputs? funny that they sanded off the part number of the eprom that loads the altera chip
  9. Way old will have to look at it. If it has the 4pdt relays, those are obsolete board file posted, everyting is the dpdt relays. So you stack 2 for stereo, and use rca to xlr adapters for the unbalanced inputs otherwise it gets stupid complicated
  10. the pile of caps could still be a pain but not for a while can't tell whether its sign/magnitude or not. if it is sign/magnitude, then its not true balanced
  11. Best news ever yamas sucks
  12. I was thinking that you would not need heatsinks. Kind of expensive to use 3 in series might be easier to use 2 of the smaller ones in parallel depending on available values i had to use 2 in series for the esx
  13. RIP Al Jarreau only got to see him once, completely unique
  14. they are wirewound, not sure how much inductance that is going to add, or whether its going to cause any trouble. I would probably use these http://www.vishay.com/docs/50051/lto100.pdf
  15. I doubt those resistors are rated for voltage, so don't mount them to the chassis, or try and find a voltage rating measure the high voltage transformer for leakage between the windings for the 900V
  16. i use the stripmaster. does teflon just fine. justin has managed to go thru a few sets of dies, mine are still original 30+ years later, although i recently bought a new one as the handles on the old one are falling apart.
  17. definitely blame me. its my fault. its always my fault. This is definitely the year of r2r and the start of the end for megabuck stupidity.
  18. i have a nikon microscope that is setup that way. For some reason i have a hard time using it due to diameter restricted optics. And i'm not going to spend $35k for it.
  19. actually i have a surgical microscope i use at work. problem is its old enough that it has no center tube for the camera
  20. That is what I use. but planning on a microscope with a had video camera not sure how well that is going to work
  21. it would be insane to use this supply to power a laptop. much cheaper to buy a power-one for the right voltage and size a number of companies now making linear power supplies to run desktop computers. they are gigantic. And with the latest 6 and 7th generation intel cpus with the 12V only supplies that are rated at 20 amps or more, also silly to do linear. no plans on crossovers. I certainly know how to do them, but lots and lots and lots of parts
  22. Any reason why you need more current than that?
  23. lower the values of the 1300 ohm resistors
