Selmer Clavioline Repair

Written by

Selmer Clavioline "Audition" Repair

I was asked to repair an ancient Selmer Clavioline, sort of a very early synthesizer. A few of the keys would stick and not play. Documented it here.

Great article on them here.

Probably 1955 if the Speaker is original which it looks to be. A valve in the unit is labelled '54 so it probably rolled out early 1955. Can't find any info on serial numbers although interestingly the hand written numbers on the chassis match that on the serial plate.

Keyboard Unit

Glued loose key (top C) back on with epoxy resin.

Realigned key pins on keyboard.

Realigned key pins on "rocker" switches.

Checked for dry joints and cleaned keyboard unit.

Slightly sanded lower rear inside end of Bakelite front name panel to prevent lower keys from sticking.

Cleaned octave range slider and tremolo contacts.

Brushed dirt from case and cleaned dust from valves.

Cleaned the keyboard.

 

Amplifier Unit

Repaired original non functioning power switch (was always stuck on).

Replaced melted polyester .001uF capacitor between output transformer and speaker with a ceramic equivalent.

Replaced mains cable with something more substantial (mains cable was not original).

Replaced what remained of vulcanised mains cable grip.

Cleaned valves and vacuumed out unit.

Rewired switch and fuse to be on the live mains side rather than the neutral side as this makes little sense now (I'm not sure it did in 1955 either!). This should be a little safer now as if the unit came into contact with an earth results would be unpredictable e.g. some or all of it would presumably become live to earth.

Notes: If you take off the two Bakelite covers on the ends of the keyboard there are trimming potentiometers which seem to set a high and low point for the tuner knobs on the side.

    I have 8 Selmer claviolines at the moment and once serviced they are sold. I have two I use in my studio. I started playing Telstar on one in the 1960's. I once again use them within my instrumental composing and recordings.
    I have quite a lot of info and photos etc on the CLAVIOLINE PAGE on my web site. This is only a hobby, not a business.

    Tijdens de winterperiode gaat de Waaier palm in een slaap, en dan hoeft hij bijna
    niet vocht meer te ontvangen. 1x per 3 dagen is dan voldoende.
    In de tussenmaanden, herfst/lente is eenmaal in de 1-2 dagen voldoende, afhankelijk van de temperatuu

    Er zijn ook periodes dat de fortunei haast geen vocht hoeft te ontvangen, want dan slaapt hij bijna, in de winter.
    Een keer in de drie dagen is dan aan te raden water te verstrekken.

    Er zijn tevens periodes dat de fortunei vrijwel geen vocht hoeft te krijgen, want dan slaapt hij bijna, in de winters.
    Vervolgens mag het wel 3 dagen duren alvorens de fortunei weer vocht nodig heeft.

    Tijdens de zomers dient de waaierpalm een hoop water te
    krijgen. We raden aan de kluit drijfnat te maken, omdat hij veel zal drinken, en de rest zal verdampen.
