CT! CBS labs, Stamford, 1963 – 1965. These CBS units still seem like the ugly ducklings of the vintage limiter market. I have had 3 of the later solid-state audimax 4440’s in the basement for the past 3 years. They work fine. No one wants em! Eventually these will be re-discovered by some hotshot mixer dude and prices will rise. The 4440 is so goddamn complicated inside, its like a fkkn analog computer. Anyone using the Audimax and/or Volumax lately? Drop us a line and let us know…
