Appendix D: Voltage Changeover and Installation of Optional Transformers
8. After wiring, mount the transformers to the side of
the chassis, using the brackets supplied with the transformers.
For the 480L outputs, we recommend Jensen JE-123-
SLPC transformers.
1. Remove R45, 46, 78, 79, 80, 82, 88, 89, 90, 91, 92,
128, 129, 130,131, and 132.
2. Install 33 ohm, 1/4 Watt, 1% resistors at R47, 81,
83, 93, 94, 133, 134, 135.
3. Move jumpers W5, W6, W7, W8, W9, W10, W11,
and W12 from position 2-3 to position 1-2.
4. Solder the four transformers into place. Note that
the transformers can be installed in either direction with
no change in performance.
