Buchla & Tiptop Audio Triple Envelope Follower Model 230t

Triple Envelope Follower Model 230t
Here’s another wonderful vintage design: three AC amplitude followers with excellent sensitivity and highly accurate CV reproduction of the incoming signal. Both sensitivity and decay time are adjustable across a wide range. The circuit is so sensitive, it can even produce output from the noise generated by rotating the sensitivity knob—pretty cool.

The pulse output can generate either a transient (trigger) or a sustained gate signal, depending on the switch setting.
