  1. square wave

    to save space I sometimes do vertical resistors. but everything else is wrong with that amp.
  2. square wave

    no servo so blackgate output caps on a solid state amplifier taking 1/3 of the board space. yep, great idea
  3. square wave

    here is why you probably don't want one unless its dirt cheap. you will need to add heatsinks, not easy, and fix all the acetate failure
  4. square wave

    the singlepower squarewave definitely does not like low impedance loads (50 ohms) making it balanced causes even more trouble. very few of the balanced versions were built, and they are balanced out only when balanced in, and depending on the power brick, they burn up real easy.
  5. Part Sourcing Assistance/Advice Thread

    definitely not.
  6. Balanced to unbalanced board

    what transistors are you using?
  7. Part Sourcing Assistance/Advice Thread

    even the ksa992/ksc1845, one of them is on backorder till February and i'm going to need them.

    Mmbt are surface mount so no you have to check the pin outs for the rest
  9. and now for something completely different part 3

    ss dynalo already has the pot, just don't populate the opamps
  10. I/V converters

    this one http://www.audio-gd.com/Pro/dac/RE52/RE5.2EN.htm around 2013 time frame. very nice sounding piece, but no dsd
  11. and now for something completely different part 3

    pin 5 on the opamp is not a NC, so if you want to do this and put a jumper from pin 4 to pin 5 on the back of the board cut off pin 5 of the opamp, or bend out of the way. the best servo of course is no servo at all as long as everything is stable with temperature
  12. stax t8000 clone (well sorta)

    better idea would be to use the servo from the kgsshv-carbon but does not compensate for the tube drifting section to section
  13. I/V converters

    so pars posted this. http://www.diyaudio.com/forums/group-buys/315474-pure-tube-es9038pro-9028-9018-akm.html#post5259820 all sorts of wrong. lets start with the fact that current output D/A converters really like driving a zero impedance. 27 ohms is not a zero impedance. So with +/-1.2ma you get +/-32mv and then you use the tube to amplify the crap out of it. Nope, definitely not the way to do this. All sorts of noise etc... a while back there was bakoon and audio-gd pointing fingers at each other as to who designed satri and when. so here is the satri version 4 circuit satriic.PDF and here is how audio-gd turns it into both the I/v converter and acss current output and voltage output (one at a time, not both) audiogdiv2.PDF performs better than anything else I have seen ideas in progress as work on the ultimate dsd/r2r dac
  14. stax t8000 clone (well sorta)

    servo attaches directly to the plate of the tube. similar to T2. no way to make less complex.
  15. KGSSHV Carbon Build Thread

    you should buy the right thing from a company that sells linear systems parts
