I bought 2 MN3007 circuit (1024 stages) on eBay and replaced the MN3209
in one of my 1-88-1Y (256) BBD modules.
I followed the procedure in the A-188-1 Adjustment Guide
<http://www.doepfer.de/service/A1881_adjustment.pdf> , but the circuit
just sat there. Seems like I did everything right, I switched back to
the 3209 and it worked, then back to the 3007 (making the appropriate
jumper adjustments and all), but I got no sound at all from the MN3007.

Is there something else I should be doing or could my chips be dead?
