Rd6000 Ic
 

Hi There,
Can anyone help me please. Due to power surge problems I have been blowing the same chip in my Airtronics/Sanwa Rd6000 transmitters and at £70 cost each time I return for repair it's getting to be a real pain. I would really appreciate it if someone could identify the eight legged IC chip nearest the crystal holder and advise me of a supplier, the markings on it are 358-802 and it is stamped with a capital N in a circle. Any info would be greatly appreciated.Thanks Guys
