Kay 830 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Kay 830 is a higher-powered model in Kay's 800 series, representing one of the larger tube combos offered by the Chicago manufacturer during the mid-1960s. Its push-pull 6L6 output section delivers approximately 25–30 watts, providing stage-capable volume for the gigging musician, and the circuit includes tremolo and a basic spring reverb system. The tone maintains the clean, warm American character of the Kay line with a broader dynamic range than the smaller 800-series models. The 830 occupies the upper tier of Kay's tube amp production and is a capable vintage combo for blues, country, and early rock applications.
