Octavia
A great transformer for consistent, clarity, low end, good octave sounds, in fact it's the best!
Made for Small Bear, 1.5K CT Primary to 500 Ohms Secondary. The red dot marks the primary. In the Octavia circuit, the Secondary is driven as if it was the Primary.
Note that when used in the Octavia, the part is installed "backwards" such that the Primary (the side with the Red dot and the Center Tap) is the Output (3 connections)
