Hey guys so I got an older American Bass car audio amplifier I am wanting to upgrade some of the older components in. Looking for some recommendations for what to use as replacement. So here is what I am wanting to replace.
NJM4558L these are the straight line pin opamps not dual inline
IRFZ44N power mosfet
Any help is appreciated. I am also replacing the capacitors on the board as well and was curious as to the effects of increasing the capacitance rating. Right no it has 2200 and 1000 microfarad caps in it.
There are 2 dip chips on this board one is a pwm controller TL494CN and the other is an opamp 4558C.
I am doing a new project. Your posting is pretty good and useful to my job.Thanks a lot. Hope you can write again.
I appreciate your article very much. Wait for your next writing.
