Just want to show a transformer set up I use in my "B" studio monitors.

Basically, it's an analog preamp feeding a pair of McCormick monoblock amps driving a restored pair of JBL 4311 monitors. These speakers are notoriously bright,
so I've inserted a pair or Western Electric 101A 600/600 repeat coils just in front of the amp inputs. They tame the brightness just right, adding a small amount of depth as well.

Note that these are not Western Electric 111C transformers. WE 101A transformers are the granddaddy of those deservedly famous111C inductors.

Since these transformers were made about 1920 and are over 100 years old, I decided to have some fun. I wired them up with equally aged WE cotton insulated solid core
hook up wire and terminated them with 100 year old WE precision wire wound 600 ohm resistors. They measure 600.1 and 600.2 ohms respectively.

The fun is using ancient technology in a meaningful way in a modern audio environment.

They sound perfect.
