Last year I built a Gyraf GSSL stereo bus compressor. I’ve been somewhat lazy regarding the documentation on this project, so I probably won’t put up much information, but here’s a little something:
The inside of the compressor. Notice the Turbo-pcb on the right side. It really makes a difference!
The front of the compressor. I've hand-dremeled the text on the front panel. It's readable, but I really wish I had a CNC-machine 🙂
The rear of the compressor. Notice the HP-logo. The enclosure is a repurposed KVM-switch.
First test of the compressor. Works really well. It's missing its front plate, so nevermind the ugly looks.
Threading holes for the screws to attach the frontplate

PARTS LIST:
GSSL PCB – Prodigy Pro Board (directly from Gustav)
Components and knobs – ELFA and eBay
19″ 1U enclosure – A repurposed HP KVM-switch. Most 1U-enclosures will do. Just be sure it’s deep enough. I also used a 1U blind panel as a front panel.
8027 WF 1mA Meter – Hairball Audio
Shielded cable for internal cabling – Clas Ohlson (Pretty lo-fi, but it works like a charm!)
