Hello! I've got the pcb and nearly all the components to start building the total recall. I'm a bit stumped on sourcing an NE570. Small bear used to have them. Has anyone tried the Cool Audio V571d? It should work being rated up to 16 volts as it is...I realize the ne 570 has heftier ratings but aside from eBay, (where I've been burned buying NOS IC's) it seems a little bleak.
