help with opamp choice for SCR

[vacuumdust]

TL074 or NE5532?  Are they interchangable?  I've done the search for the stage center reverb and there is just so much info...I can't discern (cuz me dumb) which opamp works better/quieter.  I'll be building according to the GGG schematic/layout, which lists the TL074.  THANKS

TL074 is a quad channel and NE5532 is a double op amp. Maybe use two NE5532's in it's place? Better check the pinout first though. Go to mouser.com and do a search for each of those op amps and you'll find data sheets with pinouts.
