WA6-SE (Special Edition) Headphone Amplifier
Single-ended Triode Class-A, All Tube Drive, Output Transformer Coupled
The WA6-SE is a pinnacle version of its successor WA6
Innovative design: direct interstage coupling and separated power supply
Amplifier unit on the left and the power supply unit (PSU) on the right. These 2 units work in a pair.
Front panel of the AMP unit (LEFT) has a high impedance headphone output, a volume control, and a low impedance headphone output. The knob on the PSU is a power switch.
Highly efficient and over-sized power supply designed to deliver clean, fast recovery power to the AMP unit.
On the AMP unit (front), the 2 extruded aluminum enclosures house a pair of specially hand-wound output transformers.
One the PSU (back), the extruded aluminum enclosure contains a power supply transformer.
Top view. a pair of 6EW7 driver/power tubes installed on the AMP unit, and a 274B rectifier installed on the PSU.
Back panel functionalities: PSU (left) has a AC110 and 220/240V voltage selector, a AC inlet with fuse box, and a power supply output connector; AMP contains a power supply input connector, 2 RCA audio source inputs, and a source selector. The 2 units are connected by a DC cord which is included in purchase.
