Paia 2720 analog modular synth - Pratt-Read fit Moog Arp

1970s Paia 2720 analog modular synthesizer system with modules as shown. I had two of these in similar non-working condition. I fixed one, and this is what is left. You do not need to really know what you are doing to fix these. You just follow the instructions in the manuals (all available online). It's like Legos but with a soldering iron. The components are all easily obtainable and cheap to purchase. There is no unobtanium in this. Changing caps and fixing the wiring leads alone will make most of this work. It's not a complete system, but you can interface with other modules as needed. The wood case is intact, but will need some new glue etc. It's wiggled itself apart. The Pratt-Read keys can be made flat with new bushings or could be used to repair a Moog or Arp synthesizer that has broken keys.
