AT5

Presentation

Integrated stereo amplifier

Single-ended schematic with 300B tubes

AT5 exists in 2 quality levels : see the "customisation" section.

Principle :

• Pure Class A circuit for each tube : input, driver and power

Components :

• Power tubes : 300B
• Driver tubes : 6C19
• Input tubes : 6SL7
• Outstanding  quality transformers and inductors custom made by a specialist familiar with our high level of standards.

Circuit :

• The circuit is totally simplified and for optimal signal transmission there are few components but they are of the highest quality.
• No resistive element along the signal path
• No feedback
• Very low internal impedance

Chassis :

• The chassis is manufactured using thick aluminium plates which are closely assembled to ensure perfect stability.
• All wiring is hand-wired point to point in our workshops.

Rear panel connectors :

• 4 stereo line inputs (RCA silver)
• 1 switchable stereo line output (RCA silver)
• 2 stereo outputs (WBT NextGen silver)
• Power switch On/Off/On with phase selector

 

Customization

Customisation requests must be specified when ordering.

Updating the order at the later stage remains possiblebut it includes extra shipping costs.
