I just put up a bunch of stuff on my progress of restoring a Sequential Circuits Pro-One on my website:

has anyone considered re building a pro one into a rack? Or at least a non-keyboard desktop unit? I would happily sponsor such a project......

Pretty sure it's too big for a rack. The PCB is one board and it's wider than 19". Sure I've seen one as a desktop unit.

Thanks for all the positive responses!

I'll be working on the circuit board next. Desoldering the output jack and replacing it with a new one...then lube the pots and switches. I'll continue documenting the process with plenty of photos.

Is it bad to place circuit boards on carpeting?

I'd say if you're certain the carpet is clean and the PCB has only traces on the back side, then your main risk, assuming the board has chips on it, is static discharge. A purely discrete component board with no static-sensitive solid state components, like MOSFETs, would probably be ok.
I am no longer in pursuit of vintage synths. The generally absurd inflation from demand versus practical use and maintenance costs is no longer viable. The internet has suffocated and vanquished yet another wonderful hobby. Too bad.

That would not be a good place to work on a circuit board. :shock:

I lay them down flat on a hard, anti-static surface. For smaller boards, I have a grounded clamp that holds them suspended between two arms at any angle. For things with static-sensitive components, I wear a wrist strap.

Can you tell me what you lube them with?

Also, what's the best way to clean sticky pots & switches. I hear lots of different stories what should / shouldn't be used.

Good luck with it, looks great.

Nice clean solder joints. I'm impressed with the quality of your work.

As I state on the webpage, I'm using the Deoxit Faderlube (formerly Calilube MCL) from Caig. I'm using the 5% stuff so as not to "gum up the works" with residue. The regular Deoxit shouldn't be used as it can damage some pots.
Also, what's the best way to clean sticky pots & switches. I hear lots of different stories what should / shouldn't be used.
The method I describe is good but a really dirty component should probably be disassembled to clean...or just replaced.
Good luck with it, looks great.
Thanks!
