The flanger is designed around a Reticon SAD512D (8 pin) bucket brigade delay chip, £50 to £60 if you can find one. If the Flanger doesn't work (very quiet or no signal with the effect switched on) then Murphy's Law says it's going to be the 512. The only good news is that it's in a socket. It's possible to buy a 16 pin SAD512 (without the D) a lot cheaper, but they're not a drop-in replacement.
