I need equivalent IC STRX6759

The AN8054 is an integrated circuit used in the Casio Tone Bank M120 keyboard. If it has been blown off, you will need to replace it. An equivalent replacement for the AN8054 is the LM358N, which is a dual operational amplifier that can be used as a substitute. Other equivalent options you can consider include the LM741, LM7808, and LM324. It's always recommended to check the datasheet of the substitute IC to ensure it meets the specifications and requirements of the original IC.

There is no equivalent to this IC number.

U have to replace the board, search ebay, ioffer for an equivalent

Try searching again using Google, using BT 9843, but when you look down the results ignore the two letters and see if you can find an IC which is the same numbers, even if it has different letters on the front. Those letters could be just the makers letters, with the device made by different makers.

Hey, I have seen the same problem in multiples of the Zoom processors; specially those of 505, 505 ii, G1FX, G2 and also, on a Korg (AX9000G) . I somewhere read these gears are designed to decay over time, not sure though.

However, the common symptoms of such issues are Flashing of a dot either at right or left corner, Not remembering which patch/effect it was at before getting turned off and starting over from A1 each time while powered up, Sudden cutting off or dropout of the sound while playing or strumming the guitar or whenever you strike your guitar strings, a sound like buffering comes and restart at once flashing A1, once or twice had shown up 'bt' at display etc. These are all I've heard of.

The reason for this is inappropriate power supply. This mostly happens due to electric voltage bumps and frequent changes of your home amperage and voltage, using inappropriate power supply, providing more current than 350 mili amps or crossing whatsoever ampere limit of your unit and, also, if you are a jerk enough like me who has put one end of the guitar cable at the processor input and that other end of the same cable at the processor output jack and accidentally powered the device on. (That created a chained loop at the audio amplification; eating up a huge amount of current suddenly and burnt the voltage controller of the device at once). My experience says the mosfet ic burns at first and then the resistor is burnt after a few days the mosfet ic dies.

The blinking is mostly for the damage at the internal voltage regulator mosfet ic for which the unit gets unbalanced voltage and tries to explain it by showing up that blinking. There is a 93.76854928 % chance that the resistor carrying the current to the input voltage pin for that voltage controller ic has to be burnt out due to regular and consecutive heating even upto 70 plus degrees for a long period. In most of the cases, the solution should be replacing the voltage controller IC/SMD and also, that burnt resistor right at the start of the circuit board, placed somewhere near the 9v dc jack.

Both the parts are really cheap, both the parts together might cost you around 1 or 2 USD only. Make sure you replace the exact item or the parts equivalent to the replacing dead items. For example, on a zoom 505 ii, the resistor may have been marked as R18 and equivalent to 22 ohms and the voltage regulator ic code is written as

29M33
31*1E

So, make sure to crack the parts' codes properly, if burnt out in case of resistor, check from image or video of the same product or circuit board and crack the color code of that exact parts to find the exact ohms. The soldering work is really easy or take them to someone skilled and they will fix ya. (Well, didn't mean like "they will google")
( XD )

Have a good day.

Are you sure about the make and model number?

My HTS8100 2 yrs ago stopped working properly, sound was on its max and little was heard. Well after searching for solutions and took it for repair which was a waste, my brother came from Australia for a holiday who is a technician and fixed it for me. The problem is in the subwoofer, I am uploading a photo where this part is , STRX6759 SANKEN INTEGRATED CIRCUIT STRX6759. Its behind that capasitor. When I changed it the sound worked. Hope you will find it useful.

need ic P001 equivalent

i made programmer for 89c51. in this use ic ds275. i want know what is the equivalent ic of ds275.
