So I have this old tube amp made by McIntosh for Western Electric (model# ks-19602 L1) and can't find schematic on it. Need help with the connections? It has terminal strips (7input/11output). How do I measure to find the balanced and unbalanced input taps and the different ohm output taps.
Here is the info I know: KS-19602 L1 Tube. Mono. Made for Western Electric Co.
ELECTRICAL: 25w. Response 20-20kHz (+0.5 -1.0dB). Distortion 0.5%. Noise & hum -44dBm. Output impedance 1, 4, 8, 16, 150, 200 and 600 ohms. 70.7V may be obtained from the 200 ohm output. Damping factor 10. Input impedance: 150 or 600 ohms balanced or unbalanced. 10k ohms bridging. Gain 66dB for 150 0r 600 ohm inputs.
MECHANICAL: Octal output socket for all output impedances. Input attenuators: 10 steps in 5dB/step and 0.5dB/step. Light gray.
TUBES: 2-7591 output, 6AV6, 12AU7, 12BH7. Solid state rectifier.
Size 19" rack mounting. 5-1/4"H, and 10"D. Weight 33 lb. Sold about 1963-1967. Last price ?
