Explanation of Controls

You may be wondering why the Twin Tube Classic uses a 16-volt AC transformer

instead of a common 9-volt DC adaptor or even a battery. The Twin Tube Classic

relies on an internal transformer to obtain the high voltage the dual triodes

require. The transformer cannot work on DC voltage. One alternative would be

to run the tubes on low voltage in "starved plate mode." Here, the tubes are used

like a clipping diode and do not actually amplify. Though starved plate voltage is

used in some inexpensive tube stomp boxes, it is not true tube ampliﬁcation. The

circuitry in the Twin Tube Classic enables the tubes to work like the tubes in the

preamp section of a high-quality tube ampliﬁer. Another alternative would be to

supply a dedicated AC power cord and an internal high voltage transformer or a

DC-to-DC switching converter. However, these options would make the Twin Tube

Classic larger, heavier and more costly. With the Twin Tube Classic you are getting

true tube tone AND tube ampliﬁcation with minimal size, weight and cost.
