I need help because I can't find anywhere, the UCPU ic (Pioneer PD5165A) built into the Pioneer A-701R amplifier. I really don’t know where all these ICs have disappeared from this world.
After all my searches, there should be around 28,000 pieces of this product, but when I contact the sellers, they don't even have a piece in stock, even if they have them in their offer.
I would be grateful for any answer that would give me hope to put my old friend in order.
Best regards, merry approaching Christmas
