Hi,
My humble thanks to all who provided feedback on the best approach to
take with the '5061A.
I do rather take the point about slow transitioning power not being
ideal - I think I'm mentally digging that up from a bygone era! :)
One suggestion was to at least consider using a current limited mains
source (even a 50 or 100W bulb in series) just to catch catastrophic
events at power on and/or electrolytics reforming. Food for thought there.
A common theme - reading the manual, is one I will certainly do - I was
able to locate one in among the piles of stuff and have brought it home
to study.
I will hopefully have the unit to hand in a couple of weeks, will report
back once I've got a little further.
Thank you all again,
Cheers/73
