Hi and welcome
Many owners don't realize what their Synthi or VCS3 is really able to. Aging affects performance, and the rarity makes comparing with a unit in good working condition difficult.
Pointless rumors like "A Synthi can't play in tune", "It's a wonderful noise and effects box but not an instrument" or so don't help.
This is not true. A properly calibrated good working Synthi or VCS3 tracks on more than 5 octaves and is one of the most musical and harmonic synths ever.
Also, it's infinite possibilities can be extended to more infinite possibilities thanks to some great modifications. Unlike the common implementation with extra switches, I'm able to do it without any damage and in a 100% reversible way to preserve the instrument's original condition, appearance and value. This makes it an incredibly powerful machine, with unequaled features for such a compact synth.
Only a very few techs are able to service EMS gear. I saw many units with faults preventing the instrument from working properly, despite/because these were "serviced" by techs - including some famous and renowned ones - who obviously don't know how a Synthi should work.
Many customers were just amazed when discovering their Synthi after I serviced it "Wow, I never even imagined that my Synthi could sound that good !".
Yours can too.
I have taken care of the following EMS instruments.
I stock rare Synthi components such as GEL234F1 (renamed PA234), MFC6070, TAB101, ME9002, selected 74150 or other TTL for the KS, Jones, Plessey or Bulgin connectors, Cliff K1 knobs, Shinohara meters.
I can build any special cable (umbilical, mains, CV/gate, pin-jack, modules "facilities"...).
I'm experienced in servicing other vintage synthesizers (i.a. Moog MiniMoog D, Moog Prodigy, Korg MS10, Korg MS20, Oberheim SEM, Roland Juno 106, Buchla Music Easel etc...) and other analog devices such as tape echoes, sequencers, effects.
I also do custom builds such as 208 modules.
Feel free to contact me and I'll be happy to answer any question except "Do you have a Synthi for sale ?", thank you ;)
