Traynor Mkiii Ygl3 3A preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Traynor Mark III YGL-3/3A combines documentation for the full Mark III production family — Yorkville Sound's 100-watt British-influenced flagship guitar head. Four EL34 output tubes and a high-gain 12AX7 preamp chain produce the aggressive, mid-forward tone expected of a professional-grade rock amplifier of the early 1970s. As the most powerful amplifier in the Traynor guitar lineup, the Mark III was the natural choice for Canadian touring artists who required genuine stage volume and a sound that could hold its own alongside imported British full stacks.
