Det är bara ett fåtal doepfermoduler som inte klarar +/- 15V, kommer tyvärr inte ihåg vilka.
edit: Doepfer säger "These modules will not work with +/-15V supplies: A-126, A-127, A-129/2, A-130, A-131, A-134 and A-135. These modules use the Curtis chips CEM3381 or CEM3382. The max. supply voltage allowed for these integrated circuits is +/-12V. A +/-15V supply will destroy the (very expensive) CEM circuits ! The modules A-148 (old version until end of 1998, new version from 1999 is OK), A-150 and A-151 will not work with +/-15V too. These modules may be damaged with +/-15V supplies too but the parts that may be destroyed (CD4052 or CD4053) are much cheaper than the CEM chips. For all of these modules a +/-12V power supply is absolutely necessary!"
