Doepfer

hi,
i did not understand what the problem is exactly and what you did to fix the problem. can you please explain in detail ?i have many G6's and never had any problem with grounding.so what was the exact problem in your G6's ? 
are these 2 G6's you have, new, or where modified by a previous owner ?

thanks in advance,Bakis.

    as an update.  Pulled the racks off the shelf and have them stacked on a plastic milk crate (isolated) with a dedicated Furman Merit series power conditioner.

Frame2 (expansion)
-----------------------------------
Top: RF Nomad, A-118, Multiples, A-119, A-119
Bottom: A-106-5, A-107, A-189-1, A-199, A-131

Frame1 (original)
---------------------------------
Top: A-178, A-175, A-146, A143-3, A-138c, A-144, A-178
Bottom: A-190 (a version prior to being called -1), A-160, A-161, +5V adapter, A-189-1,A-148, A-156

Patch set up:
RF Audio Out -> Multiples ->A: Morphing Filter -> VCA; B:-> Bit cruncher -> reverb -> VCA
Random voltage CV ->RF Nomad
LFO2 CV-> Morphing filter (frequency)


Testing:
- patches worked on the old frame as described
- Re-verified the internal wiring of the G6 power supplies to the bus boards/ground to chassis and they look correct.
- Cables are not the problem. I've tried multiple cables and they all come to matching results.
- Putting the CV from random noise triggers the desired response in the Morphing filter.  Same with manual control.
- Moving the LFO2 to frame2 triggers the desired response in the Morphing filter.
- Adjusting the LFO2 rate or the attenuator in the Morphing Filter has no effect while the LFO2 is in Frame1
- Using QuadLFO or therimins as CV source instead of LFO2 nets the same results.

Still stumped on what is keeping the signals from these frames to be out of whack  #yiv4024721881 #yiv4024721881 -- #yiv4024721881ygrp-mkp {border:1px solid #d8d8d8;font-family:Arial;margin:10px
