Tsakiridis Aeolos Tube Amplifier | 35W–70W

Description

Tsakiridis Aeolos Integrated Tube Amplifier

The Tsakiridis Aeolos is the best-selling integrated amplifier family from Tsakiridis Devices, combining classic vacuum-tube architecture, handcrafted transformers and practical everyday operation in a compact design.

Built around a push-pull Class AB1 topology and dual-mono power supply, the Aeolos range is available in four versions: Aeolos, Aeolos Plus, Aeolos Ultra and Aeolos Ultima. Output power ranges from 2 × 35W to 2 × 70W, allowing the amplifier to match a wide variety of loudspeakers and systems.

Push-Pull Class AB1 Design

Every Aeolos version uses two power tubes per channel in a push-pull Class AB1 configuration. This topology combines the tonal qualities of vacuum-tube amplification with sufficient output power and control for real-world loudspeaker systems.

A dual-mono power supply helps maintain strong channel separation, while carefully positioned power and output transformers reduce unwanted magnetic interaction.

Four Aeolos Versions

Aeolos – 2 × 35W

The standard Tsakiridis Aeolos uses four EL34 output tubes and four 12AT7 driver tubes, delivering 2 × 35W.

It includes four line-level inputs, one pre output, motorized Blue Alps volume control, gold-plated RCA connectors, remote control and handmade output transformers.

Aeolos Plus – 2 × 45W

Aeolos Plus increases output power to 2 × 45W and uses four 6550 power tubes.

• Power Tubes: 4 × 6550
• Driver Tubes: 4 × 12AT7
• Output Power: 2 × 45W
• Power Transformer: Handmade 300W
• Output Transformers: Handmade 8-layer windings
• Signal Capacitors: High-grade polypropylene

Aeolos Ultra – 2 × 70W

Aeolos Ultra moves to four KT150 output tubes and delivers 2 × 70W.

It also introduces upgraded signal-path components and premium loudspeaker terminals for higher-power systems.

• Power Tubes: 4 × KT150
• Driver Tubes: 4 × 12AT7
• Output Power: 2 × 70W
• Power Transformer: Handmade 400W
• Output Transformers: Handmade 8-layer high-quality core
• Speaker Connectors: WBT-0703 Next Gen
• Signal Capacitors: Jantzen Audio Superior-Z

Aeolos Ultima – 2 × 70W Reference Version

The Aeolos Ultima is the most ambitious version of the range. It retains the KT150-based 2 × 70W output stage but adds premium signal-path parts and Tsakiridis’ top 16-layer output transformers.

• Power Tubes: 4 × KT150
• Driver Tubes: 4 × 12AT7
• Output Power: 2 × 70W
• Power Transformer: Handmade 400W
• Output Transformers: Handmade 16-layer, 6N copper, high-quality core
• Speaker Connectors: WBT-0710 Next Gen
• Signal Capacitors: Mundorf Supreme Silver Gold Oil / Rike Audio QCap4 Copper Oil
• Assembly: Silver soldered by hand

Remote-Controlled Integrated Amplifier

The Tsakiridis Aeolos is designed as a complete integrated amplifier, allowing direct connection of analogue source components without the need for a separate preamplifier.

The supplied aluminium remote control provides convenient access to volume adjustment, input selection, mute and power-tube bias functions from the listening position.

Combined with the motorized Blue Alps volume control, the remote system adds modern everyday convenience while preserving the amplifier’s traditional all-tube signal architecture.

Rear Panel and System Connectivity

The rear panel provides four line-level inputs, a preamplifier output and high-quality loudspeaker terminals. This allows Aeolos to function as the central analogue amplifier in a complete high-end audio system.
