HIWATT DG 103

  Based on the Custom 100 head, but with special modifications as commissioned by Dave Gilmour of Pink Floyd himself, the DG-103 adds a bit of modern sophistication to the classic performance amplifier. In addition to the Bass, Treble, Presence and Master Volume controls, the DG-103 uses a specially linked input system, where the gain of each channel can be altered to suit different musical styles. Built using Partridge transformers, 4 – ECC-83 tubes in the preamp section, 4 – EL-34 tubes in the power stage, and is rated at 100 watts output, with switchable 4-, 8-, and 16-ohm impedance.A look inside the amplifier will reveal point-to-point hand wiring, turret tag boards (no printed circuits), and hand laced wiring harnesses. The power and output transformers are manufactured by Partridge, the original 1970s supplier to the original design sheets. The components and wires are the modern equivalents of the vintage components, 1-watt carbon resistors, and wound polyester capacitors being used throughout.
