A collection of synth related schematics, collected by
vladosh on the
forum and copied to here by
Blue Hell and vladosh.
There is an automatically maintained sorted index
here.
You can search the Vault through the search box above by using a search expression preceded by Schematics/ e.g Schematics/lfo to search for LFO's.
Note on Copyright:
electro-music.com always respected the great amount of work, effort and time invested by individuals in making a better synthesizer ,better designs . One can be only grateful that folks that spent their lifetimes in electronics are willing to share their knowledge and findings with the public . This thread will only try to serve as a wider reference to synthesizer schematics for better understanding or for inspiration for the next module.
