Mount the PSUG/Really Big Heat Sink Assembly to the Chassis
Mount the PSUG/Really Big Heat Sink assembly to the chassis using two 6-32x3/8"
screws. One of the screws goes into the newly drilled hole. The other screw goes into the
slot. The screw doesn't really quite fit into the slot, but you can screw it into the slot with
your screw-driver. You could also use a rat-tail file to open up the slot just a bit.

Note that for the ultimate heat transfer, you could apply thermal compound to the bottom
of the heatsink.
Inspect for clearance
Inspect your work, making sure that none of the components on the PCB has leads that
are touching any metal surfaces outside the PCB. Refer to the cover illustration for the
orientation of big capacitor clamps if you should find that there is interference.
Make sure that there are no miscellaneous bits of hardware or wire floating around the
amplifier.
Testing the Result
If you power up the amp, you should see 72 Volts of DC across C12 after the slow start
time has expired. Please be careful to stay clear of the high voltages inside the
amplifier.
Turn off the amp and pull the plug before going on. Wait 2 full minutes before
continuing.
Reassemble the amplifier
Return the mounting foot to its original hole. Note that the mounting foot is now separate
from the RBHS mounting. The mounting nut fits between the fins of the heatsink if you
put your added hole in the correct place. Replace the cover and install the 4 screws that
hold the cover in place.
