The bright channel runs a full-range signal. The two “channels” are then added together with a summing circuit, and from there on to the output section, which consists of two EL84 pentodes running in class AB (pushpull) configuration, and a very beefy output transformer. The power section uses a 6CA4 (EZ81) tube rectifier and a likewise very beefy power transformer. Other front panel features are two 1/4” input jacks, one labeled “high,” the other, “low” (both feed both preamps), an On/Off switch and a Standby switch. The rear panel reveals an IEC power plug jack (for the separate power cord), two fuse receptacles, a three-way 4/8/16-Ohm speaker impedance switch, two speaker jacks, a “pentode/ultralinear” switch (more on that later), effect send and return jacks, and a plugged hole labeled “footswitch” to be used on a future model. The chassis top shows us three 12AX7s (the first two being preamp tubes and the third the phase inverter), the previously mentioned output and rectifier tubes and transformers, plus a major-sized choke and two very large filter caps.
The chassis interior reveals very neat point-to-point and turret board solder joints. All small components, including the tone circuits, are mounted on the turret board, a nice reliability touch. The caps are high quality, and the resistors are low tolerance. The CTS pots are full size and have the look and feel of good quality units. The cabinets are sturdily built from multi-ply Baltic birch plywood with dovetailed corner joints and covered with black Tolex accented with white piping. The grill is an attractive woven fabric. There are heavy metal corner protectors on each and every corner. A large, Plexiglas Lone Wolf (howling at the moon) logo graces each cabinet, with the top one being back-lit at the flip of the power switch—too cool!
The speaker cab is loaded with two 12” Celestions: one Vintage 30 and one GH-12, both with 50oz ceramic magnets and 1.75” voice coils. Add the weight of the cab and the head and we come up with a total amp weight of 79lb. Before talking about the sound of this specific amp, it might be good to gain a bit of historical perspective. Back in the late fifties, Vox released the first amp designed for rock and roll: the AC15, which utilized, you guessed it, the EL84 output tube. They wanted to get away from the country and blues amps so heavily favored in the US and come up with something different for the burgeoning rock market. The EL84 has a tight (but not necessarily punchy) bass, a chimey mid, and sparkling highs—and when pushed, sounds downright raunchy.
