Hi Gaz,

I am learning too but my thoughts are:

It may be that although the new PS can supply 15v the Caiman only draw what it needs from it, basically like a reservoir. To work in this way it would need to have some form of internal tracking regulation (I think Stan may have called it a virtual circuit in a past note?).

It may be that this regulation differs in the Caiman and 7520 models and if so it would be best to check with Stan before going for it.

Just my thoughts.

Regards

Chris
