hi ravpeet,
with the 3k preset turn to clockwise about 2 o clock position and check with .33/5w resistor.
only one mistake in the pcb that one 18k/2w resistor
above .33/5w resistor.

i am about to start making this M10,and hunting for the componends like IR2117, NJM4580,
Just wanted to ask can i use HER207 insted HER204,205,

nazirdigi · 1st June 2012, 08:07 AM

HER207 instead HER204,205, yes u can.

what purpose Ur going to make this amp? for business or for yourself.
because i am asking this, the transformer is the main thing. its expensive.

for business u have to make the casing like professional casings, if u can, make it, otherwise its useless, u cant sell. wasting money and time.

for self use its ok.

I don't know about business. as i have said i am not a professional amp maker. its just my hobby. i love music. A LOUD MUSIC. and yes i know the main part is TRANSFORMER. but for me and for my HOBBY, money is no matter.
