What is the poblem with sockets ?
I often repair 106s, so mine has voice #1 on socket just to check the 80017A of the 106s of my customers. No problem until today... Image
The making of my modular... (ok it's in french, but the pictures are easy to understand !)

I don't think there's a problem with sockets if you use the right ones....
Some techs (respectable ones at that) say sockets cause more headache and increase the chances of dropped voices. I assume this means that there's a chance that the sockets won't hold the chip tight enough, and a bumpy car ride can unseat a chip.
I find this plausible.
However, in my experience using nothing-special sockets, it's never been a problem. Not even once.
Roland pcbs of the era were not great. If a chip failed, I would not look forward to de soldering and re soldering a second time to replace a chip. Plus, sockets make it that much easier to use AR chips in the future. It's a good compromise if you're can even call it a compromise.

I think the sockets are a very nessersary, I have removed countless Juno at chips and the tracking is very fragile.

I see many sad cases from botched attempts on those boards...if you can't solder don't try it.

Got 3 in this week for new chips.

Top tip.....always remove the deadly foam from the pot board...and clean out the sliders.

That's what it comes down to.... If you can't solder, more so de-solder, don't try it. You will burn the board. You will lift traces. You will cause more problems.

The foam is now days brittle. We're getting it remanufactured right now and will have it available soon.

Yes I agree, for a 106 on the road, it is preferable to solder. 8-) Mine is in "studio use" only.

True. Hot glue does the trick though. Sent one on tour with some silicone for extra protection. Not one problem on the road. I've shipped them around the world with a small dab of silicone. No problem.
Interestingly enough, the mid tier sockets I get, generally, will hold the chip tighter.
Forgive me for my synths.
