[sdiy] Juno-106 replacement filters

[KRiSh]

I have a 106 with 1 VCA always "open".

I already replaced all sliders (19 sliders including the Bender ones) + all
34 switch to it.

Feels like new now, only that voice is needing repair now.

I have rescued 4 voices from a friend's Juno that are supposed to be
working (he decided to change all of them with the AnalogReinassance ones).

My intention would be to remove the broken voice, then soak in acetone the
broken one and the working ones,
then try to fix the broken one and if not successful then swap it with one
of the other working ones.

To do this easily, i'd like to find a 12 pin socket that does not require
the original terminals of the voice cards to be removed and resoldered with
other terminals compatible with common sockets found around the web while
looking for solutions on forums videos.

Those sockets have bigger holes than the originals on the board, thus
needing thicker terminals, but we all know removing and resoldering
terminals on those voices is potentially dangerous for the integrated
circuits aside (you don't want to heat them too much...).

Never found discussions about board level resoldering afterward nor about
death of the voices depending the date code actually:
if you have links to them please share.

I always thought that the epoxy on the voice modules is causing overheating
and that is what causes the slow death of the rare unobtaniums custom ICs
underneath.

I'm still investigating on this, probably after restoring
