THORN G53417.T 150w SON Ballast

Another one rescued out of the skip, this tests out fine electrically so should work ok. I think it's unused but has been sat around for many years. The metal casing is a little bent up, but the core itself is undamaged.

This is rather large for a 150w ballast, it's dimensions being similar to a typical modern 400w SON ballast! The actual core is only the standard size one would expect, they've just added extra casing for some reason.
