Title: Do transformer end bell covers reduce noise?
Post by: boogieWoogie on December 02, 2018, 10:01:31 am
Hi folks,
For Hammond transformers, often there's a choice between a power trans. w/ endbell covers, and one with a nylon bobbin & no endbell covers.  Are the covers known to reduce noise, or are they cosmetic.  AFAIK, they're steel, not mu-metal.

Thanks!
