"Untested assembled PAIA 4700 analog modular synthesizer with 2700 and 8700 series parts.
These kits were assembled in the 1970s and installed in a wall cabinet in a basement den.
The manuals were stored in a garage and at some point got wet, but were dried out and have been in
dry storage for 25 years.
The modules were removed from the wall cabinet 25 years ago and have been stored in boxes
in dry storage ever since.
These modules are unrestored, untested and have not been powered up in decades. The modules
will be bubble wrapped individually for shipping. Please email with any questions or clarification on
modules labelled as "xxxx" that cannot be determined from photos.
