Hi Manoj:
I also given your file (ver 1.1) to make PCB. Should I halt that untill you correct the design- if needed?
Thanks

Hi Hadi,
AUD600-Rev1.1 there is nothing see any error on PCB.cross checked every track,only i changed 2x 47k 0.25W replaced to 1x 100K 1W and 1k 1% changed to 1K trim pot and added temp switch provisions
For this trim pot do not set to zero Ohms (shorted) minimum value is @200 Ohm.And first setup is, trim pot set to 1K value. other wise remove trim pot and fix a 1k 1% resistor.
I think you are done a mistake something has happened may be component value change or track shorted etc... re-check again
Regards
MANOJ

Hi
you change 10uf 100v cap with 1uf 100v too and some chage too near ir ic
PLZ wait for stewin amp
if he have like me error then must chek again
i dont use trimer
i use 1k 1% and 1k 1w
i must send to you my picture
i use 80 turn around T106-2 and conect the filter to board
i dont here like this before and every thing is good and cold.
not heat any things
the sound is so cleare and very good
i must say very very very thanks sir manoj
i like to have your new vertion
can you please send it to my email ?
thanks dear friend

HI HADI,
YES I AGREE THAT, BUT NOTHING WILL HAPPEN WHEN YOU CHANGE THE VALUE 10uF/100V TO 1uF/100V THIS IS VB SUPPLY FILTER OF IR2110 FOR USING HIGH SUPPLY ie.+75V OR MORE YOU NEED TO REDUCE THE VALUE THAT IS WHY I REDUCED TO 1uF/100V.
NOW YOU CAN INCREASE THE FREQ. TO 300KHZ AND TEST IT FOR THIS FILTER YOU REDUCE TO 47uH.
REGARDS

Hi sir manoj
IRFP250 work in 250 KHZ
do you want use it for 300 KHZ ?
why ?
how can i creat 47uH with T106-2 ?

Hi hadi,
irfp250 you can use up to 330khz
its for only test, and the quality also increase

how can i creat 47uH filter ?
how much turn aroud the T106-2 with 0.8mm wire ?
what about the resistor value for change the FREQ 300KHZ ?

Hi hadi,
T106-2 winding Calcultion (uH = n^2 x Al /1000) so 47uH = n^2 x 13.5 /1000
59 Turns for 47uH
resistor, i don't know the correct value(don't remember). 820 Ohms or 680 Ohms

thanks sir manoj
i need a preamp for your amp
do you have any sugestion ?
i need to reduce noise in your amp
thanks

hi all
those who are experts in irs900d. is this the correct version ? and which resistor can one adjust the switching frequency?

ir2184 class d amp
hi to all,
Greetings,
any one try lm311 ,ir2184 class d amp schematic, if try how is work.
ir2184 is not available so any possible to change ir2184 to ir2111.
Thanks in advance.

hi sweet
ir2110 schematic is large size its suitable for high watts but i want 300 to 400 watts for my 12" single sub woofer with compact size and low cost so i will try ir2184.

Hi stewin,
it is 1k resistor connected between two 1nf capacitor(near TL071) to GND

Hi kirubakaran,
non UCD type will give you sound better in high and low freq. compare with UCD one
