INTRODUCTION Congratulations! You have purchased one of the most exotic vacuum tube audio integrated amplifiers available. Within its power range, the CAD 300 SEI integrated amplifier offers the most realistic sound reproduction one could desire for a “high-end” home audio system. Careful design, parts selection and proper circuit topologies contribute to the incredible reliability and enjoyment. For the technically minded, a review of the circuit is in order.
INTRODUCTION The most exciting feature of the CAD 300 SEI, aside from how compact and gorgeous it looks, is the delightful, sensual beauty of the music it recreates. The first thing that will strike you about your CAD 300 SEI integrated amplifier is the incredible transparency and resolution of detail of the music. The CAD 300 SEI sensual nature is best revealed in the sense of life it displays in female vocalists.

INSTALLATION This section describes the unpacking and installation procedures for your new component. Unpacking All Cary Audio Design shipping containers have been specially designed to protect their contents and special care has been taken to prevent damage under normal shipping conditions. Mishandling should be evident upon inspection of the shipping container. If shipping damage is found after visual inspection, take care not to destroy the evidence.
OPERATION Signal input connection is made via the input jacks on the rear of the CAD 300 SEI located next to the output binding posts. The interconnect cables from the output of the preamplifier can be any convenient length your set-up requires. The choice of a high quality interconnect cable is important. Once again, your audio dealer will have the proper cables in stock for this purpose. Your new CAD 300 SEI is ready for operation after the speaker, interconnect cables, and the tubes have been installed.
DIAGRAMS Bias Adjustment Insert the meter plug into the bias jack. Adjust for 150 mA to 160 mA reading on volt ohm meter or DC current meter. Re-adjust the setting after the amp has warmed up for 10 minutes.

DIAGRAMS Tube Placement Chart CAUTION Large pins on the 300B output tubes must be inserted into the large holes in the tube socket. Failure to follow these instructions will result in serious damage to the tubes and amplifier and is not covered by the manufacturer’s warranty.
SERVICE AND CARE The chassis may be cleaned with a soft towel and Windex® or a similar window cleaner. Spray it on the cleaning cloth to moisten it, not on the component. Do not use solvents or harsh chemicals to clean the preamplifier. They may remove the labels from the chassis. The frequency and need of cleaning will be governed by operating environmental conditions. Avoid letting the component become dusty or wet. A ‘feather duster’ type cleaner will also work well for cleaning the component.
