Alamo Montclair - Tremolo preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Alamo Montclair is a tube combo from Alamo Electronics of San Antonio, Texas. It has two input pairs: a normal channel and a tremolo channel, each on a 12AX7 stage with its own Volume and Tone. A further 12AX7 provides gain stages and the tremolo oscillator, with Speed, Intensity and a footswitch jack. A 7199 works as driver and split-load inverter for a push-pull pair of cathode-biased 6V6s, with a 5Y3 rectifier and standby switch.
