Check and Test Your Work

You're about to check and test your work. Please recall that there are potentially lethal

voltages in the amplifier. Please continue to work safely.

1. Make sure that the AC cord is still disconnected from power.

2. Verify that the positive terminals of the new C9 capacitor configuration are

connected together.

3. Verify that the wires connected to the positive and negative terminals of C9

cannot, under any foreseeable circumstance, come into contact!

4. Place the rocker power switch in the SCA80(Q) in the ON position.

5. Plug the amplifier power cord into a power outlet.

6. There may be the usual "bong" as the amp powers up, but there should be nothing

else notable.

7. After 30 seconds or so, check the DC voltage on the new C9. Although it isn't

regulated, it should be somewhere in the range from 68 to 76 volts if everything is

working correctly. The nominal voltage is 72 Volts.

Safety First – remember to unplug the amplifier and let the capacitors discharge before

working on the amplifier. These new caps will hold charge for a long time. It's safe to

work on the amp after the new C9 voltage is less than about 12 volts.

Remove the power cord and wait one full minute before proceeding. Reinstall the

amplifier cover using the five sheet-metal screws that hold it in place.

Once you've placed the amplifier back in service, you may notice the following:

1. It takes a little longer for the power supply to reach full voltage (a few seconds).

2. Upon turning power off, the amplifier will continue to produce sound longer than

it previously would.

3. More extreme low bass power will be available.
