Hi Brad,
A while ago I received a private message from Dan G. to make me aware that the can of C401 is floating at a negative supply.
I appreciate very much his use of the private message to avoid embarrassing me here for having overseen this important detail, even when at my age I have lost all shame, ha ha.
I had assumed, without certainty, that C401 is the same part as C430 and C431 just mounted on an insulating sleeve. But there are no drawings in the maintenance manual, and I could be wrong.
I was always the project designer engineer, and someone else did the product engineering. There was always collaboration, but different perspectives.
This is why I can easily be wrong in my opinions here.
Ernesto
