CAVE PROJECT! This information is here to support people who have been making MFOS gear since I started
posting synth-diy information back in about 2002 or 2003. These projects have ALL been superceded by new and better designs. I do not
recommend that you make these since they have been improved over the years. I am not providing any support
for these projects beyond publishing this historical information.
This is an intermediate to advanced project and I do not recommend it as a first
project if you are just getting started in synths or electronics. Only the circuit and some explanation
are shown here. A lot of project building experience and electronics knowledge and equipment ownership
(scope, meters, etc.) is taken for granted. If you are interested in building this project please read
the entire page before ordering PC boards to ensure that the information provided is thorough enough for
you to complete the project successfully.
Updated and Improved VCO With LM394 Super-Matched Pair
Same as the other new oscillator except uses LM394 Super Matched pair and a separate OP-Amp for the pulse
wave. Remember to mount R3 (TempCo) in contact with the LM394 case.
