Sca80 Directions; Removing The Amplifier Modules, All Versions - DYNACO PWRAMP80 Assembly Manual

SCA80 Directions

If you have an SCA80, then follow these directions.
8. There are two ground lugs that were fastened to the chassis by the mounting
screw on the C9 side of PC-19.
a. Find the lug that has two black wires that go to the amplifier modules and
one white wire that goes to the negative terminal of C9. Cut the white wire
that goes to the negative terminal of C9 near the solder lug.
b. The other ground lug has a bare wire and two white wires that connect to
the COMMON terminals of the speaker connectors on the back panel. Cut
off the bare wire, but leave the other two white wires that connect the lug
to the COMMON terminals. This ground lug will be re-attached in a
future step.

Removing the Amplifier Modules, All Versions

1. Desolder and remove:
a. All wires connected to C9 RED terminal.
b. All wires connected to C9 BLACK terminal.
If you've installed a C9 replacement kit consisting of a dynamite configuration of 3
capacitors, then leave the wires that connect these capacitors in parallel in place. Only
remove the wires that leave the capacitors for other parts of the amplifier chassis.
