  1. 47uf tants are fine with 25V, but 10uf ones should go up to 35v or above
  2. nice build ~ BTW , a friend of mine bought your first build,pretty happy about it
  3. nice. 恭喜台灣 DIYer 再+1名
  4. yes I read this before so I thought this board should work, was thinking maybe I need to use other smd resistors which has higher wattage rating?
  5. digging up this thread ... has anyone build smd version of ubal and buffer? I built mine ,when firing it up , leds did lit up and smoked instantly picture as attached .not quiet sure whats going on yet. I use diffinput3smtd and dbuf3 gerber files to make curcuit boards
  6. about 130*65mm max od.for pre-reg cap is 30mm tant and opamp compensate caps are moved to the backside of pcb
  7. I used thruhole ver in previous build and I'm sure I'm gonna use smt version next time........
  8. Looks like some soldering issues to me,especially with tps7a regs
  9. congrats yes cold joint will be affected by temperature and cracks very slowly,that's why it occurred few days after you've done your build
  10. actually I tried 992/1815 from project spare parts .With some simple matching you can still get low offset results sounding is also not bad tho will keep trying other combos
  11. too bad,the county I live (台東) has no THSR . May be you can have a quick meet with joehpj or others
