The CS-805A amplifier boasts exquisite craftsmanship with its handmade point-to-point silver wiring, guaranteeing exceptional signal integrity and reliability.

For convenient and precise bias adjustments, the amplifier includes an on-board bias meter, simplifying the process for users.

Furthermore, the CS-805A provides the flexibility to adjust the negative feedback, allowing users to fine-tune the amplifier's performance and tailor the sound to their preferences.

Product Description:

The CS-845A is a single-ended, pure Class A integrated stereo amplifier featuring 845 output power tubes, delivering twenty-four watts per channel.

This all-tube amplifier incorporates the renowned WE6SN7 tubes for voltage amplification, 300B tubes as driver tubes, and 845 tubes as output tubes, ensuring exceptional audio performance.

On the rear panel of the amplifier, you'll find three pairs of line inputs, a pair of pre-in inputs, and a pair of tape outputs. The pre-in inputs offer the flexibility to connect to an external preamplifier, enabling the CS-845A to be used as a power amplifier.


Speaker terminals for 4 and 8 ohm speakers are conveniently located on the rear panel of the amplifier.

To facilitate bias adjustments, the CS-845A provides user bias controls specifically designed for the 845 tubes. Additionally, a meter has been added to the top plate, allowing for easy monitoring of the bias levels.

For convenient adjustment of the hum level of the 300B tubes, the hum balance control is accessible on the top plate of the amplifier.

The CS-845A also features a negative feedback switch on the front plate, providing the option to choose between two levels of negative feedback (NFB) and enjoy different sound outputs from the tube amplifier.

In the 0dB state, the CS-845A exhibits an open sound with enhanced details. Switching to -3dB results in a softer, cleaner sound.

With its anodized aluminum front panel, fully vented chassis, and exquisite finish, the CS-845A exudes elegance. Its construction incorporates meticulous hand-made point-to-point wiring.

To protect the amplifier and extend the life of sensitive components, a soft-start circuit is implemented.

Premium components, including an Alps volume control, audio-grade capacitors, carbon film resistors, a toroidal transformer for power supply, wide bandwidth EI output transformers, and ceramic tube sockets, contribute to the amplifier's exceptional performance.

The CS-845A is equipped with a remote volume control and has the capability to memorize the last operation performed when the unit is switched off, providing added convenience to users.
