Silver and Gold.

My favorite UPS man left me my X-mas present a few days early in the form of a large box filled with gold.

Add a few pounds of silver and you end up with something special.

Without a size reference it is hard to tell exactly what you are looking at but let me just say that is a very large 80% nickel 5K output transformer that will do around 3W full range!

For reference, most people consider moving one size up from the autoformer size is a big 80% core.  Well these babies are 6 sizes up and sounding wonderful with a 2A3 playing Elvis's Christmas.

Happy Holidays to all!
