SEQUENTIAL CIRCUITS

How can I tell what revision my Prophet 5 synth is?

Refer to the list of serial numbers below:

SERIAL # REVISION #
0001-0182 1
0184-1299 2
1300-2285 3.0
2286-2423 3.1
2424-2451 3.0
2452-2455 3.2
2456 3.0
2457-2465 3.2
2466 3.0
2467-2476 3.2
2477 3.0
2478 —> 3.2

If you don’t know the serial number of your Prophet – as a rough guide: Rev 2 – has no heatsink on the back – the Rev 3.0/3.1 – has heatsink but no “interface” sockets Rev 3.2 – has heatsink and two interface sockets to the right of the heatsink (as you look at the back) Rev 3.3 – as 3.2 but has IEC mains socket and 120 programs instead of 40
