Pics of the inside below.

"1981 Rev 2 Sequential Circuits Prophet-5. This is the early revision which features the SSM oscillators, filters and envelope generators. SCI switched the design to Curtis because SSM could not supply their need. Many Prophet-5 fans will tell you that the SSM filters are more interesting than the CEM filters. This synth sounds great and is in great condition. The factory patches have been loaded and it has been recently serviced. All switches, pots and LEDs work as expected. The keyboard buss bar and j-wires were cleaned after the new bushings were installed. The keyboard plays very well. The metal nameplates are in good shape on the front and back, the plate under the control panel was replaced with a new one.
upgrades and service

New rubber keyboard bushings
Kenton UK MIDI kit (In/Out/Thru) - the only midi kit for the rev 2 from what I understand.
Cassette In/Out for patch dumping
Power supply mod which reduces the need for the -5v and +12v supplies, EPROMS replaced
New battery
All this work and calibration was done by a former SCI tech in the bay area."
