Hello-
I've just acquired a 200 -- trying to understand the switch function.
From what little is in the manual, and looking at the front panel, it would seem that the two "on time" controls should function similarly; on this unit, the B control seems to affect the switching speed, while the A control is switching waveshape.
Does this indicate malfunction of the module, or do they all work that way?
Thanks.
