Definitely worth restoring! That’s an amazing find. One of the earliest, fully electronic instruments.

I’d read about these in Tape Op I think, in an article that documented a project by Wally De Backer (better known as one-hit wonder Gotye) to find, restore and play one of these. Ultimately, he did a limited number of shows with what he called his “Ondioline Orchestra”. Really a cool project seen through to fruition.

In the video linked below, he talks about the project, the restoration, etc and plays a tune on it that could be straight out of a Warner Brothers cartoon from the 40s.

That’s a piece of history you’ve got there. Keep us posted on the restoration!

Whether you think you can or you think you can't, you're probably right.

Oh wow, this is the vibrant keys sound in Del Shannons "Runaway"? https://www.youtube.com/watch?v=wSWMJxbxj7c wrong again  :o, its a very similar sounding instrument, the Clavioline!
This wonderful instrument got a lateral vibrato keyboard in 1950s! Awesome project!

Hi all

Yes a nice pce of history, come after Martenot and Theremin but very interesting design for keyboard tremolo/expression as percussive pad or knee bender

I have this one since 2 or 3 years (an offer I can't refuse) but never star the restoration.
Now I start, first disassemble everything for clean and visual inspection...

As I say I'm not used to tube except basic microphone clone, I'll do this slowly to not make any bad move, I have to learn things in the mean time ...
I expect a year or so, using spare time, reverse engineer to draw schemo etc...

I find some schemo but it seem mine have way more component count, have to check better

Also I don't know what I need to change, for sure EL capacitor (there is a dozen including dual 8uf) but I read paper oil have to go too, no idea for substitution yet, but I'll find easy wits little search.

I notice one "bad" thing, most if not all solder joint look matt, I suspect global cold solder joint  :-\
What is the good practice for this, remove all and new solder ? or just flux and heat again ?
This is a 60+ years instrument  ::)

I doubt that all the solder joints are cold. If the builder used non-eutectic solder (not common back then, but it was sometimes used) then the joints would be less shiny than with 63/37 eutectic. Plus they’re old and dirty and even if eutectic was used some surface oxidation is to be expected.

I’d probably get after them with a brass wire brush and lightly clean them. For really dirty joints, some contact cleaner and a toothbrush might be called for. Once cleaned up, it’ll be easier to evaluate their condition. You may need to reflow some. But personally I wouldn’t be inclined to reflow all joints unless I ran into a gremlin during testing.

Whether you think you can or you think you can't, you're probably right.

Hey Rackmonkey

Tks for the input ! I'll try that when I start this topic on the Ondioline restoration

Very nice ! How did you run into one ?  You're in France ?

The Ondioline was  consign to me by a friend, she play "onde Martenot" profetionally.
By that time to check it, but due to heavy work needed on it, the restoration was too expensive so she decide to give it to me to restore it when possible  for me, obviously if I succeed to finish this work I'll lent it to her, so she can use it in studio or for various project (maybe not for live show...)
I don't have the story of this ondioline before that, she bought it but don't know the full context, IIRC a flea market for few bucks  ::)
(Yes I'm in France)

Hi Zam,

Very nice, nothing beats the feeling that you ran into something weird/special/obscure/costing-next-to-nothing at a flea market! :-)
... followed by several years of storage
... followed by pulling it out of storage and finally restoring it!

I like those weird instruments, wishing you a nice restoration project, please keep us posted here!

Bye,

  Peter
