i wrote billion times to check every detail and just after to solder in board. to check the polarity of all diodes,
transistors. measure every resistor and capacitor.
NO REACTION. THE LAZINESS. i waste a time on idiotic job.
look on this diode. why you so believe chineses and chinese componets? why? why you consider if chinese did draw
a strip there is alway the cathode???

Guys

i again ask you do not use WD40 and any oil in pots. VERY ASK AGAIN. the electronics is NOT the cars how you assume.
you think if you use WD40 that will be better, NOT AND NOT! thats BADLY. i waste a time on opening cleaning of your pots.

I NEVER DID OFFER TO USE OIL IN POTS. NEVER.

WD40 sucks

For potentiometers there is contact oil


I use Kontact61 with great success
