Alps switches

Alps switches

2010-01-28 by jfloydhumanoid

Hi, all,

Does anyone know where I can find 5 or 6 of these?

alps_switch

They measure appx 100 ƒ¶ when closed, ‡ open. Anyone have any old stock? Or know if any old computer keyboards can be cannibalized?

Thanks.

Look for tactswitch on the internet.
If you can take the top off there'll be a lot of replacements.

or

Check this at ALPS/mouser datasheet and see if pinout/size matches

If you can find something that fit the bottom, you can probably craft the 
plunger part out of plastic standoffs or similar.

Thanks for the help, folks!

I'll order a few different switches & see if anything will serve as a replacement.

Mini-Moog Keyboard Question

2010-02-20 by Samuel Adams

Hi,
 
I'm a new member to this group and am in need of assistance.  
 
I have a 1973 Mini-Moog that I put in storage about 10 years ago in my attic
in the original case. At that time, it was working fine.  [Attic is
insulated and doesn't change temperatures too extremes - maybe 50 degrees in
winter and 90-95 in summer]
 
I recently took it out, turned it on and noted that the keyboard doesn't
work...Keyboard will trigger the oscillators, envelopes and the rest fine,
only won't change notes...Single note sounds throughout the keyboard
compass.  
 
Pitch bend works fine but no note change with the keyboard, only single note
will sound.  This seems to be the only problem.
 
I did leave it on for a few days and took the circuit boards out, applied
DeoxIT on the contacts and reinstalled them to see if there was some type of
corrosion had developed but to no avail. 
 
I'm not all that technically experienced and don't have a service manual so
I have no idea where to start, asides form cleaning the board contacts. 
 
I live in upstate NY, near Saratoga Springs and can't find a service tech
nearby to take it to.  
 
Any suggestions? 
 
Thanks

It sounds as though the power supply has died!

IF power supply died, why does everything except the keyboard function
properly?

I'm no great expert on electronics, but i understand minimoogs, particularly early to mid manufacturing period, suffer from oxidation and corrosion to the rocker switches. This, i would guess (and this is a guess) could be the cause of your problems if the rocker switches on the mixer section aren't contacting properly - you could try an appropriate contact cleaning spray on these?

Re: [vintagesynthrepair] Mini-Moog Keyboard Question

Hi Sam,
I would recommend a look at the 6 pin keyboard interface connector that lurks under the modulation\pitch bend section.
The silver plating on these Cinch-Jones connectors corrodes easily.
The connector is quite stiff, use a small screwdriver to prise it apart.
A good scrub with wadding silver polish of both sides of the connector and a final clean with isopropanol should cure it.
Obvious but also check for a broken wire at that connector.
Regards
John

I second this. Did you try the CV inputs? If the CV changes the pitch it has to be something about the keyboard connector.
