Bogen DB-110 Texas Blues Special preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 'Texas Blues Special' is a Bogen DB-110 PA amplifier converted into a guitar amp. A single input feeds two cascaded 12AX7 stages with a three-way cathode-bypass switch, a dual-gang Baxandall bass and treble control and volume. A second 12AX7 drives and recovers a spring reverb with level, and a third provides a gain stage and paraphase inverter for two 6V6s with a pentode/triode switch and switchable cathode bypass, on a 5Y3 rectifier.
