Hi all,
I'm new to the forum, and excited to be a part of the community.
I'm having a perplexing issue(to me) that I wonder if someone may have some insight into. I'm using a bridge rectifier to provide negative voltage to a bias/heater circuit in a tube amp. I'm also using the same supply to power a relay through a buck DC/DC converter. Its working, but with some issues. I've connected the +/- leads to power the DC/DC converter, but it isn't reducing the output of the rectifier, in other words, its acting as a pass through. My thought is this due to it not having reference to ground. I don't want to mix grounds, as the positive lead is grounded on the rectifier to provide the negative voltage for the bias . I'm thinking of removing the (-) lead to the DC/DC converter from the rectifier and routing it to ground instead to complete that part of the circuit. Does this sound sound?
Thanks!
Mike
