Cheshtap Power Amp

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.

hi ravpeet,
check this.

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,

 

[wattaniya]

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.

What is BUSINESS

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.

thanks for the schematic nazirdigi,how many watt's in 4 ohms this big amp,is 2 ohm's load possible?

 

[wattaniya]

1500w on 4ohm with mjl21195/96 or mjl4281, 2ohm load possible.

 

[sandeep kayarkar]

sir, which thermal switch u use in this amp?
and which pcb track has to be cut?
THANK YOU

[sandeep kayarkar]

tell me some one which track has to cut?

 

[electra_ina]

nice work...

 

[wattaniya]

sir, which thermal switch u use in this amp?
and which pcb track has to be cut?
THANK YOU

i use 80degree celcious thermal switch
u check post no 42 and u have to cut pin in relay.

 

[sandeep kayarkar]

sir
u mean this pin?
