Karaoke Delay

I’d been thinking about adding some FX to the rack when I discovered this dirt cheap karaoke delay board on eBay via a post in one of the synth DIY groups on Facebook, which uses the PT2399 digital “bucket brigade” chip.

I ordered one from China for about £4 and followed the instructions I’d found to convert it to Eurorack format, replacing the power header and the jacks and wiring it all up.

I mounted it with a cardboard panel to begin with, making an acrylic panel for it later.
