all I know is that they were made in Ohio, Stow I believe actually. I read an article in a tapeop about a couple people (husband and wife I believe) who run a studio with a flickenger, or they had a flickenger.... some info in the article. I'll look for it tomorrow, or maybe someone knows more off hand.
They seemed to really love the flickenger console, .... I believe they helped steve albini build electrical audio iirc.
