Juno 106 to Capacitator???? HELP

Post by KennaOkoye » Thu Dec 08, 2011 9:51 pm

Okay the white wire in the picture to what i think is the capacitator came undone. How do I put it back together? I have a soldering gun... I think that's all it needs. I don't trust electrical tape. It looks like the black wire is on already. Help! thanks

In case u don't know what that part is... on the other side of the grey is where the plug from the wall is pluggined into... without that white wire, the board does not power on

So often I have posted: "Take it to a tech..."
But, I'm betting you CAN DO this !

Get the end of the white wire hot with the gun, then melt a little solder onto it.

Put the gun on the terminal where the wire will go and wait for the solder on it to melt.

Keep the gun on the terminal and hold the wire against it until the solder on the wire melts into the solder on the terminal.

Pull the gun away WITHOUT moving the wire or terminal. Let the joint cool for about 10 seconds.

CONGRADULATIONS !! You've repaired a vintage synth !!


EDIT:
Now... If you want to do things like this on a regular basis, go buy a 25-30 watt solder pencil. Then you can begin learning soldering skills.
Doing this right would have involved removing the broken piece of wire from the AC power connector (not a condenser), stripping more insulation from the wire, placing a short piece of heatshrink tubing over the wire (you would probably need to cut the plastic wire tie), wraping the wire thru the hole in the terminal (like the broken end was) then soldering and lastly, sliding the heatshrink tubing back over the solder joint and terminal and heating it.

Great!
IMHO the first rule of learning to solder well is: The heat must be right. Being able to judge that by sight is a challange at first.

The 1.1 rule is- it must be mechanically sound before you apply solder. Meaning- the wire should remain connected without any solder. The solder is reinforcement.

Agree 100%, but the correct series of steps (in the edit) might be pushing a newbie too far. Took the chance that in this case, "gobbing" it on would get him going again. Later, he can go to a tech or get in a little practice on some junker.

watch a coupla vids or tutorials on soldering. Get a cheap iron, some solder, wire strippers, and some wire nippers (miniature diagonal cutters) and a solder sucker or wick and small needle nose pliers.

I like to use a smidge of tinning flux on a large gauge wire like this to ensure proper flow.

Heat the lug 'til the solder starts to melt, remove the solder with the wick or sucker, remove remaining wire fragment on the lug, you may need to heat it to keep the solder flowing while you do this. Strip back the loose wire enough to attach it to the lug. insert the wire into the hole in the lug (it there is one) and bend/crimp the wire on there so there is a decent mechanical connection. You may use a bit of the flux here if you feel it'll help. Sometime when you wanna get in quick without melting your housing the flux can help solder to flow more quickly. Don't over heat the lug/wire.

Don't blow in it to get it to set faster. Just be still.

I could go into more detail but that's the gist.
