The main power transformer (toroid) part: 150-r1107010in the
TSS-SUB4000 is not mounted in the amplifier inside the amp cover, but mounted
in the cabinet in a separate location.
To replace the power transformer, it is necessary to remove the woofer
from the cabinet. The mounting bolt and transformer itself is mounted on an
internal brace; both are accessible through the woofer opening.
Troubleshooting:
To keep the circuit “live” while exposing the amplifier
components, the amplifier cannot completely be removed and powered up outside
the cabinet due to the power connections to the externally mounted transformer.
Instead, an alternate method is to leave the amp cover in place and remove the
four Phillips screws holding the amp ass’y to the amp cover. Then the amplifier
can be partially removed for access, while maintaining the power connections.
Unplugging the LED connection (red/black wires) at the PCB plug will allow the
amp to be removed even further.
