Hi Allen
I also use regulated mains adapters for my astronomy equipment and I label each one either:
Centre pin +ve, or…
Centre pin –ve
…as most of my gear is designed with the centre pin positive whereas my Vixen mounts have the centre pin as negative and I believe they (vixen) do not have reverse polarity protection which is a barbaric practice by modern design standards IMHO.
Cheers
Dennis
