PLEASE READ THIS MANUAL BEFORE ATTEMPTING TO OPERATE EQUIPMENT!!

1. Carefully lift the amplifier by the bottom cabinet edge out of the shipping carton. Place the

amplifier on a firm, level surface and carefully inspect it for shipping damage. Contact the

shipper immediately if any damage exists. Do not discard the carton or packing material.

2. Remove the twelve screws holding the cover on with a number 2 phillips screwdriver.

Carefully lift the cover off the amplifier. Save the screws to resecure the cover.

3. Locate the fuse pack with the two 12 amp fuses and fuse caps. If additional screws are

needed, they will be in the fuse pack also. NOTE: Fuses supplied are for 120/110/100V

operation. If you are rewiring the AL-811 for 240/230/220V operation, you must use 8

amp fuses. The AL-811X export model is pre-wired for 240V operation and is supplied with

8 amp fuses.

4. Remove the foam packing material (left side, front view) that secures the 811A tubes during

transit. Carefully unwrap the tubes. Do not dislodge the Aluminum shaft that is connected to

the rear input bandswitch wafer.

5. To install the tubes in the sockets be sure the large diameter pins line up with the two large

diameter holes in each socket. Do NOT rock or twist the tubes excessively during the

installation.

If the tubes are already installed, check the tubes for proper seating.

necessary, press the tubes down into their sockets with gentle force. Do not rock or twist the

tube(s) excessively. Also check that the anode caps are secure and did not come loose during

the unwrapping process.

6. The white ceramic anode connectors will have to be removed from the top metal cap of each

tube if it ever becomes necessary to remove the tubes from the amplifier. This can be a

difficult procedure because of the high clamping force of the internal springs in the anode

connector may hold it to the cap very tightly. The tube will break if direct upward or rocking

pressure is applied in an attempt to remove the connector. The safest way to remove the

ceramic connector is to lift the tube out of its socket. A twisting or spinning pulling motion

can then be applied while holding the ceramic connector firmly until the tube and connector

are separated. Repeat the procedure for the other tubes.

7. Install the cover with the vent holes to the left (near the tubes) by installing the back screws

first. Install all the screws loosely and tighten them only after all the screws are in place.

8. Install the fuses and fuse caps on the back of the unit. Read the manual to become familiar

with the operation of the AL-811 amplifier.
