The only difference between the BT-4 and the BT-6 is the number of
tubes and the voltage capabilities. The BT-4 takes advantage of a
combination style tube where the single tube contains the pentode and
triode. Whereas the BT-6 uses a 3rd tube per channel and the pentode
and triode are in different tubes. The sound quality of both ampliers is
outstanding.

Installing Tubes
Installing the tubes is a quick and simple procedure.
First, the old wives tale that you should never touch a vacuum tube is
false. While you should never touch a hot tube as you may suffer burns,
touching a cool tube with your bare hands is just ne.
1. Take note of the position of the pins on the bottom
of the vacuum tube. You will notice a section with no
pins. The pins that are there will correspond with the
pin holes on the socket on the amp.
2. Using your bare hands line up the pins with the
holes on the socket and apply a slow rocking even pressure until the
tube is seated.
3. Continue this process until all tubes are installed.
4. On the BT-6, the short fat tubes should be installed in the two front
holes.
