If you set the 5.333V rail correctly, the 1V/oct output is pretty much bang on.  The oscillator is surprisingly stable too.

Considering they were a (comparatively - nearly a grand, in today's money!) low-cost instrument made from pretty low-spec components, they worked surprisingly well.  Although, those dual trannies couldn't have been cheap!
