I have a Crate VC508 guitar amplifier that many recommend modding by replacing the TL072CP opamp chip. I got a TI NE5532 off ebay. It's supposed to be a stright up replacement but it's about a third of the size. The TL072 is around a half inch rectangle with 8 legs going into a socket. The NE5532 also has 8 legs but is less than half the size. I need a low noise drop-in replacement for the TL072CP (I broke one of the legs removing the original). Any suggestions?
