ECB Audio Labs

Vintage Audio Restoration — Charleston, South Carolina

ECB Audio Labs is a personal, hobbyist restoration effort focused on classic audio equipment from the 1970s and 1980s. Each project is approached with careful electrical and mechanical restoration, quality components, proper adjustment, and thorough bench testing.

The goal is simple: preserve these classic pieces, document their history and restoration, and return them to reliable, great-sounding condition for another lifetime.

“Restore it as if
you were going to
keep it forever.”
