[Perry Babin]

It looks like the MIC4426 and TC4426.

thanks for the quick answer¡¡

but, There is another circuit I can use? because here is dificult to find this circuits and i cant find one with that part number


thanks¡

I know of no other drivers that would be the same. You'll have to order them if you can't get them locally.

Take your caps lock off and keep it to this post and see what happens. Multiple posts not required.

Good luck.

i have looked at my zx 1000.1 turns on great but no output i have no scope so i cant drive power hat way is there another way???

If no one else can help, start a new thread and I'll try to help. I won't reply in a thread for a different repair.

I don't understand the statement about powering the amp and the scope.

hi, im back, i replace the ir4426 with tc4426, and the optos 2601 with the 6n137, i have all voltages ok, but the output fets are not working.
i put a wire betwen rca shield and amp ground, not sound.
about 110volts on the outputfets, so the PS is working fine
what i should to check??

 

[ray9043]

i see in other post how to check the out pin in the preamp, i do this:
put a 100mhz signal with a player conected to the rca inputs,
turn on the amp relay engaged and checked is ok
check the volts in the gnd and out pins on the preamp

i have -0.47 volts on this pin, with and without signal, i know something is wrong, but i dont know who is or where start to check.

 

[ray9043]

i check the voltage witch dc, not ac¡
now i check with ac and i have 0.01 to 0.70 volts in ac, but i change the gain pot because the other person who want to repair the amp stole me this pot, so i change with a common pot of 20k, i solder only 2 pins, the pins who change the oms from 0 to about 20k, so its ok but this pot is 20k or other value???

 

[ray9043]

i check the voltages on the out pin again, i read from 0.5 to 6 volts, so i know is ok. now what i should to check??

 

[Perry Babin]

Do you have a rail-rail square wave on the output transistors?

 

[ray9043]

i try to get a oscilloscope to check that, but where i need to put the probes to check that??

 

[Perry Babin]

Just make sure that you have rail-rail swing on at least one leg of each of the output transistors.
