I'm about to start requesting quotes from transformer manufacturers for my DCPP mono amp. It will be a C-core or EI type power transformer to match my output transformers.
When getting a custom power transformer built how beneficial is electrostatic shielding? Also, I have read comments that an electrostatic shielded transformer needs to be properly grounded. Is it as simple as connecting it to the PCB ground? I don't think the original Hammond 290FX has a electromagnetic shield.
I'm already aware of the benefits of external shielding with a copper flux band. And I will be requesting that.
