together and nothing bad will happen.
With your speakers and line level source connected, you can turn the amplifier on by flipping the
switch on the rear. The switch on the front is not the power switch, but rather a bias adjustment
for the input tube. It may be operated in either position, but should be changed only when the
amplifier is turned off.
After allowing the amplifier to warm up for a few minutes, you can slowly raise the volume (also
located on the rear)to the desired listening level.

DURING OPERATION

After about 30 minutes you will notice the amplifier getting very warm. This is intentional, the
higher temperatures brought on by the pure class A operation push the fidelity higher. Some
areas of the chassis may be hotter than others. This is normal. However, proper ventilation is
recommended. If you operate the amplifier inside a cabinet, allow a minimum of 4 inches on the
sides, and 10 inches above if possible.
The output tubes have a glass temperature of 200 degrees centigrade by design, and you can
be assured that they will be that hot if you touch them or your cat decides to lick one.
This is important to consider with the rather extremist option of front input jacks. Naturally if you
use these jacks, routing of your interconnects is important. If they touch the output tubes, they
will surely melt, unless of course you have our silver/Teflon cables that will not melt.
The last heat related comment is this - turn your amp off when your not using it. Tube life is
directly tied to hours of operation so there is no point wasting it when your not listening.
INITIAL BREAK-IN EXPERIENCE
Unfortunately the esoteric parts in this SELECT amplifier besides being extremely fast, also
need to break-in. The combination of a fast amplifier and fresh parts can be a little rude so we
will explain the process.
Specifically it is the exotic capacitors that actually require the burn-in to sound right. The fastest
way to achieve a burn-in is to play the amplifier for 5 hours and then turn it off and let it rest for
