  1. Tested my 10k UL PP output for EL156 PP with frequencies and square wave curves response. with inductance tested with LCR meter score from 100HZ-10KHZ 15-20k.mp4
  2. in old school we use Ferric chloride Ferric cholride in common layman name is a kind of iron salt,uses for some industrial water processing and not for consuming.
  3. sim lim tower basement there is a company doing it,you can check with their price. But if know how to DIY PCB you can do it yourself.
  4. You need to understand how is this GM70 work on the Ia vs Va curve and give you a full power drive.
  5. 白牡丹 another vinly LP
  6. Taiwan 70s 闽南 folks song 素兰小姐vinyl LP Rock n roll version by 伍佰
  7. Saints local band during the 70s,one of a major band in Singapore music records LP industrial here. $3 find today at the records shop!

  8. Thanks for compliments! Selling my handcrank winder for half mth already but no taker,haha...
  9. A power transformer winding based on old school presence,i wind them from scratch.... Usually found in the oid days English transformers in the early 60s.

  13. It is a turns ratio also in this case application for power transfomer. In theory without consider any core losses.
  14. message me you will get the full formula. Is (pri voltage/sec voltage)squareX?+(?x150) for example if you want to try a 230V to 6V transformer to use as an output what is actually you get for your pri impedance?I will tell you is 11K if you connect to a 8 ohm spk.
