Title: What step down transformer to use?
Post by: Oddvar on August 04, 2019, 06:03:12 am

I have a .50 Caliber amp from Mesa running on 110v.  I need a step down transformer, but I am a bit uncertain about what to use?  What to look for?  Any advice here?

Schematic shows a 2.5A fuse with line voltage of 117V. That suggests 292.5VA. I would look for a step down transformer rated at least 300VA.
