Description

authentic RCA bakelite knobs modeled from vintage units!

These are exact replicas of the vintage 1.5″ and 3/4″ RCA knobs used on the original Universal Audio 176 Vari-Mu Limiting Amplifier. We meticulously reverse-engineered original RCA knobs from a vintage unit and had them cast in Bakelite (!!) specifically for our 176 kit.

There are plenty of cheap pseudo “RCA-style” plastic knobs out there—we’ve tested them all. Not only do they look nothing like the originals, you can immediately tell by the weight that they’re just plastic. Our analogvibes RCA knobs are not only visually spot-on, they’re also made from real Bakelite—just like the originals—nice and weighty.

Hands down the most authentic 3/4″ RCA knob re-creation you’ll find!

This style of knob showed up on a bunch of legendary studio gear back in the day, the kind of hardware that basically shaped the sound of recorded music as we know it. The most iconic example? The Universal Audio 176 Vari-Mu Limiting Amplifier — one of those all-time classic pieces you’ll still find in high-end studios and collections today.

We kept everything as close to the original as possible — from the material and weight to the overall feel — so when you put this thing on your gear, it doesn’t just look right, it feels right too. Proper vintage vibe, no shortcuts.

They’re made for 1/4″ shafts, come with the analogvibes branding, and we had them custom-made specifically for our Limited Edition 176 Vari-Mu Limiting Amplifier Kit.

You can grab individual knobs, or save a bit when you go for a bundle.
