Thanks Paul,
Yes it’s an Isolation trans, not balanced, Two leads in, two out. There is a filter network on the output two 15uf caps from hot-neutral-ground and a resistor small cap in there as well. I have not had a chance to take it out and trace it out.
The center bolt was insulated but it made me nervous and I have already removed it.
I think it will work well for my power amp. Now I am looking to integrate it with my low power stuff. Maybe carry on with the Felicia or maybe add a couple of CMC to the output outlets…John
