“ETI 4600 synthesiser With Elektor Formant Modules. Condition is “For parts or not working”.
This synth will require a lot of work, potentially a rebuild before it can be considered working. It would cost too much to pay for a tech to bring up to scratch so should only be bought by someone with good technical skills and knowledge and a lot of spare time.
You will need to find schematics for it.
Please do not bid if you are expecting a working synthesiser. This is a project that will need hours of work and testing to ensure it works properly and safely.”
