Missing ic U247B kit K2606

Hello, some time ago I bought an ancient Velleman kit, the K2606 Led Audio Power Meter but after opening up de package I could not find the led driver ic.
I tried to order it online but couldn’t find it here in Europe, is it maybe still possible to order it via Velleman or could I easily replace it with a different one?
Thank you very much in advance for your reply.

Sorry, we had to discontinue this kit in 1997 because the driver IC’s were discontinued by the manufacturer.
Unfortunately, we have zero stock.
