The Ampeg GVT5 (110 combo and head) is a 5-watt single-ended tube amp from 2011. Its one ECC83 (12AX7) runs two cascaded gain stages around a passive treble, bass and volume stack, driving a single cathode-biased 6V6 into an output transformer with 4, 8 and 16 ohm jacks. The standby switch doubles as a full or half power selector.
