It was almost too easy to add this rack of 4U modules in Loudest Warning panel format. All I needed to do was to make a 4U rack frame. The frame is just a pair of 84hp Eurorack rails with M3 square sliding nuts, held together with a pair of 4U rack ears. The ears were the hardest part to source. Thankfully I was gifted them. Left to right, above:

• Slightly Nasty Model Asymmetric Slew Limiter
• Slightly Nasty Model Discrete Oscillator
• Slightly Nasty Model 2251 Multiband Filter
• Hale Modular VC SLEW LIMIT/LOCK
• Low-Gain Mix-Pro
• Low-Gain Dual Low Pass Gate + Mixer + Preamp
• Low-Gain Dual Negative Slopes + Hills and Valleys

Though I called it a Serge project, that’s something of a misnomer. The only true Serge module is the Dual Negative Slopes + Hills and Valleys. However the LW panel format is inspired by Serge. The banana jacks are like Serge. The Asymmetric Slew Limiter is inspired by the Serge DUSG. And the VC SLEW is inspired by the Serge SSG.

Here’s the specification for the Loudest Warning format:

These modules run on +/-12V. I took a rack case that used to hold MOTM modules and tweaked the Power-One analog supply down from +/-15V. This case also houses and powers the Dual Benjolin project.

The whole rack is easily removable. Here’s a picture of the back.

Modules above, left to right, are in the same order as listed above. The green PCB is the Hale VC SLEW, which is the only module bought assembled.
