Vintage Synth Repair

Hi!

my minimoog started acting op the other day!

it plays the same note nomatter what key im pressing!

is there an easy fix, 'cos i'm on tour at the moment, and can't wait 
for a tech...

any suggestions would be great!

thanks! D

Hi D ,
  It sounds like one of the keyboard contact springs is permanently 
making contact with CV buss bar . Remove the bottom cover and check to 
see if the bottom keys' CV spring isn't clashing with the CV buss bar  
(thats the rod towards the front that runs the length of the keyboard ) 
.

Many thanks

hi!

just wanted to let y'all know how i fixed my mini!

i screwed off the bottom plate and inspected it... as i couldn't seen 
anything wrong i unplugged the connecter form the keyboard to the 
rest of the of the synth! it was really oxidiced, so i decided to try 
to clean it with some steelwool! after i did that and put everything 
baco together my minimoog is playing perfectly again!!!!

i decided to go ahead and do the same thing with all the connectors! 
it made my mini less noisy and more stable!

-just wanted to let you know

Hi Daniel

 

Not normally to be recommended as these connectors are usually plated with
some form of precious metal, could be gold, rhodium or silver.  Wirewool
will remove this plating and the connectors will probably give a lot more
trouble in a short time.  The correct method of cleaning is to use a contact
cleaner/lubricant.

 

I only hope you haven't done too much damage.

 

Regards

 

Brian

oh oh!!!
hope i didn't ruin something!

i only scratched it lightly though! otherwise i'll have to replace 
those connectors if they start to fail... 

thanks for your advice!

by the way. i wouldn't dream of using steelwool on the printboards! 
i've used an eraeser on that, but it was to big for the connectors, 
so i couldn't use it...

Daniel

*Never* use steel wool to clean up connectors.  Even assuming a steel hair 
doesn't short out something you'd rather not have shorted, you're 
coating/embedding the contact with steel, which *will* rust.  It may work 
well for a while, but you've guaranteed future trouble.

If mechanical cleaning is necessary, I'd recommend ScotchBrite instead of 
steel wool.  I cut a pad or strip, squirt some CAIG Labs ProGold or DeOxIt 
onto the ScotchBrite, and then do the rubbing.  Seems not to leave any bad 
things behind, and if you don't get too aggressive (ScotchBrite comes with 
a range of grits, just like sandpaper and steel wool) you'll leave the 
plating on the connector, assuming the plating survived the corrosion that 
caused the poor connection in the first place.

It's really a pity that connectors didn't use stainless steel; would have 
prevented a lot of problems.
