turn_off_problem

Hi
After I have spent a lot of time trying to fix a problem on my B-3
without succses, I have decided to ask for help in the mailing list.
My B-3 is a late US-model, propably 1972. I have convert the B-3 
from 60 Hz to 50 Hz using the Trek II module. I have also installed
the connector kit 6122 for Leslie 122 / PR40 (Hammond-Suzuki).
The organ works good except an unpleasant appereance :
When the organ is turned off, then it occured in the speakers (Leslie or
PR40) a big noise (bang). The same if just the PR40 is connected
(w/o connector kit) and the same using an other PR40. I suppose
the "peak" is comming from the G-G terminal of the B-3 preamp.
When only the Leslie is connected and the connector kit is switched
to ORGAN, then the organ can be turned off without bang.
Does  somebody have an idea ? I would appreciate any help.
