Unpacking, Setup, and Connection
Unpacking the amplifier
Carefully unpack your HA-2 amplifier. Inside the package, you will find the amplifier
chassis, the tubes (packed separately), a power cord, and this manual (guess you already
found that, huh?) It’s always a good idea to save the original packing material.
Installing the tubes
There are three different tubes used in the HA-2. Note the tube types, which are printed
on the tube boxes. Referring to the drawing below, remove each tube from it’s box and
install it into the corresponding socket on the amplifier. The tubes are keyed, so rotate
the tube until its key matches up with the one on the socket, and press it down into the
socket as far as it will go.

Make sure that the tubes are installed in the right locations. DOUBLE-CHECK! If you
turn the amplifier on with the tubes in the wrong spots, you will likely ruin the tube, and
may do damage to other amplifier components as well.
Connecting the amplifier
Plug the power cord into the amplifier, and the other end into a wall outlet. Connect the
audio inputs of the HA-2 to your CD player, pre-amp, or other source, using standard
RCA-type audio cables. Note that the input connectors are color-coded, red for the right
channel and white for the left. Plug your headphones into the connector on the front.
You’re ready to listen!
