Lectrolab R600 - Channel 1 preset
Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.
The Lectrolab R600 is the largest and most powerful model in the Lectrolab lineup, delivering approximately 35 watts through a push-pull pair of 6L6 output tubes. Designed to serve the touring and club market of the early 1960s, the R600 offered the headroom needed for ensemble playing at a price accessible to working musicians. Today the R600 and its rebadged equivalents are recognized by collectors as capable vintage American tube amplifiers with broadly useful tone for blues, country, and early rock styles.
