Very nice find!

Some really nice schematics - of special note is the diode ring VCA on page 113 - I wonder how good the CV rejection is.

You´re welcome! The VCA is exponential because of the diodes, right?
The 0,1u cap blocks DC except some initial thump, right? So is a good CV rejection depending on the symmetry? Maybe with feedback adjust on the inverter and matched diodes?
On the same page the author´s comment to the circuit is that the distortion isn´t very intolerable so the device could be used in very simple systems of moderate compromise... maybe he´s hinting at the signal going through the diodes. Perhaps bypassing the input attenuation would make it a voltage controlled fuzz... Smile

You´re welcome. Not bad for a free edition of a 1975 book, right? Wink It also explains how some basic stuff works in a very accessible way. For instance I finally got to know how phasers work. And further on there´s a more thorough section on how to build a modular synthesizer, with complete schematics.

I just noticed the IC is a 747 dual opamp, not 2 741s.

It´s a bit obscure, isn´t it?

Thanks mucho! Now I'm going to have to brush up my Spanish and learn the audio and electronics vocabulary.
